all: Reeftown Rangers reporting for fun!

- Well, hey there, Reeftown Rangers!

Well, if you'’’re looking for fun, you are in luck, because today is Kelp-Fest!

- It is?

Whoa!

What is that again?

- Well, it'’’s a big party.

Even a sourpuss like Chipper gets excited for Kelp-Fest.

- Mildly.

- [groans] - Well, we were gonna play some games, but Kelp-Fest sounds great!

We'’’re in!

- Yeah!

I love parties!

all: Party!

Party!

Party!

- Well, okay, then.

The only thing we need to do is clean this place up.

- We'’’ll help you, Tidy.

- Yeah, and then we get to celebrate Kelp-Fest!

- All right.

Let'’’s do it.

- Yeah!

Kelp-Fest!

That'’’s it.

All clean.

- Are you kids ready?

all: Yeah!

- To clean some more kelp?

- No, no, no, Tidy.

It'’’s time for Kelp-Fest.

It'’’s a party.

- That'’’s right.

Kelp-Fest is a cleaning party.

- Oh...

Boy, this Kelp-Fest thing is an emotional roller coaster.

- It'’’s the one day a year that we garibaldies clean every single solitary kelp leaf from top to bottom.

- Every?

- Single?

- Leaf?

- Oh, it'’’s a shame that this day only comes once a year.

- Okay.

We'’’ll get busy.

- Yeah.

- [chuckles] ♪ ♪ - What'’’s that?

- Wow.

- What is it, exactly?

Is it a big seashell?

- Well, it definitely has a shell.

Maybe something lives in the shell.

- If something were living inside of the shell, wouldn'’’t it be talking or moving or-- - Oh, boy!

Kelp-Fest is not the day to have mystery creatures that do not belong here lying on my kelp.

Oh, they'’’ll laugh me right out of the kelp forest.

- Ha-ha-ha!

Good-bye!

- Oh, Chipper, now is not the time, thank you.

- Tidy, why don'’’t we take this whatever-it-is away from here?

- Ooh, what a great idea.

I can always count on you Reeftown Rangers to do the right thing.

- Although first we have to figure out what it is.

- Well, that'’’s true.

Boy, you kids are helping already.

Thank you.

all: Bye, Tidy.

[all speaking at once] - [laughing] - All right.

- That'’’s great.

- Let'’’s figure out where this little guy belongs.

♪ ♪ Okay, so whatever this is has a shell, but isn'’’t a shell because, well, the part in the middle'’’s kind of squishy.

- Oh, yeah.

It is squishy.

Whatever it is, it must not have bones.

- Yeah, and these look almost like... [tinkling and whooping] [all gasping] - This thing is alive!

It'’’s blinking.

- Oh, boy, I'’’m sorry, sir-- or madam-- or, well... we didn'’’t know you were a living creature.

- Yeah, are you okay?

Can we help you?

- Okay, so it'’’s alive, but it doesn'’’t talk.

- How are we gonna figure out what it is?

- Well, maybe we can figure out what it is by figuring out what it isn'’’t.

- You can say that again.

all: Flo!

- Hey there, kids.

Splash, you may not have realized it, but you were on the right track.

- Really?

I mean-- [clears throat] Of course I was.

But just so everyone else understands, how was I on the right track?

- The best way to figure out what this creature is would be to first figure out what it isn'’’t.

But instead of going creature by creature, you can go group by group.

- Group?

You mean like how we'’’re all fish?

- You got it, Dunk.

A group is made up of organisms that have similar features.

- Oh, like how we all have fins.

- And all fish have bones... or cartilage, like sharks.

[both laughing] Hey.

- Oh, Splash, you'’’re right.

We do have bones.

- Yeah, and we know that this guy doesn'’’t, so that means-- - It isn'’’t a fish.

That'’’s one group down.

all: Yeah!

- Nice job, kids.

You'’’re off to a great start.

Now, if you'’’ll excuse me, I need to head to the surface to breathe.

Bye, now.

all: Bye, Flo!

- So what other group could this be?

- Well, there are lots of them.

We just have to think about-- ow!

- Think about what?

- Right now, I'’’m only thinking about what just stuck me, but I don'’’t see anything.

What could'’’ve pinched me?

- [groans] Hey, Bubbles?

Listen, I just want to say I am very sorry.

- For what?

- Well... - Ow!

- That.

- A sea urchin.

Wow.

That'’’s another group!

Sea urchins are echinoderms.

- Oh, you'’’re right!

I love echinoderms like starfish and sea cucumbers, with their tiny little feet.

- Yeah, this creature doesn'’’t have those.

This has a lot of different parts.

And a shell.

- Yeah.

Echinoderms don'’’t have shells.

- Well, doesn'’’t sound like our friend here is an echinoderm.

That'’’s another one off the list.

Way to go, Reeftown Rangers.

So what other groups are there?

- Hmm.

Shell... shell... [gasps] Hey!

Crustaceans have shells.

- Who do we know that'’’s a crustacean?

all: Hmm... [all gasping] - Hmm.

Never seen a creature quite like that before.

You think it'’’s a crustacean?

- Well, actually, we were hoping you could tell us.

- It'’’s got a shell like you or a crab or a lobster, and they'’’re all crustaceans, so-- - True, but its shell doesn'’’t cover its whole body like a crustacean.

- [mumbling indistinctly] - Very good point, Maury.

I didn'’’t think about that.

- What was that?

- Oh, he was just saying how this creature has tentacles, not legs like a crustacean, so sorry kids.

Not a crustacean.

So it might be a cnidarian.

- A cnidarian?

You mean like an anemone or a jellyfish?

- Ooh!

I saw some jellyfish over at takeoff point when we got here.

- Oh, well, let'’’s go!

Well, thanks, Denny.

And thanks, Maury.

- Good luck, kids!

- [mumbles indistinctly] - Bye.

- Yeah.

- What?

It can swim?

- We'’’ve been carrying it this whole time.

- Don'’’t remind me!

My poor fins.

[moans] - All right, you guys.

Well, one less thing to worry about.

Now, let'’’s go see Wave.

Come on.

- Yeah!

- To Wave!

- [mumbling] - Hey, Wave.

Hey, have you seen any jellyfish around here?

- Hey, there, kiddos.

Jellyfish, huh?

They'’’re always around somewhere.

- Okay.

Well, if you see any, can you let us know?

- Sure.

Say, who'’’s your little mollusk buddy?

I haven'’’t seen him before.

- Oh, that'’’s just a-- wait, did you say mollusk?

- Sure.

He'’’s a mollusk if I'’’ve ever seen one, and I see one every day, if you know what I mean.

[chuckling] I'’’m talking about me.

Also a mollusk.

- Oh.

So it isn'’’t a cnidarian like the jellyfish?

- No, no, no.

Definitely a mollusk.

In fact, we'’’re both cephalopod mollusks.

You can tell because we both have tentacles.

Just like yours truly, invertebrate all the way.

- But what about the shell?

You don'’’t have a shell.

- That'’’s true, but a lot of mollusks do, like sea snails.

Yep, looks like a good old-fashioned mollusk to me.

- You have no idea how old-fashioned.

all: Gush!

- Gush, what do you mean?

- Your new friend here is an ancient creature known as a nautilus.

They'’’ve been around for about 550 million years.

That'’’s why they'’’re known as living fossils.

all: Wow.

- That'’’s even older than my dad.

- That'’’s amazing.

- Nautiluses live deep down in the ocean and don'’’t come up this far very often.

He probably got separated from his family somewhere, and then you found him.

- Aww.

Poor little nautilus.

- Deep down, huh?

Hey!

I know where to take the nautilus.

Okay, little buddy, well, your home'’’s down there in the deep.

Do you want to go home?

Sorry.

Mortimer'’’s a little shy at first, but once he warms up, he'’’s a little chatterbox.

No bouncing backwards this time.

Don'’’t let yourself get turned around there.

[whimpers, inhales sharply] Dunk dive!

Whoo!

[laughs] I did it!

I mean, of course I did it.

[laughs] Wasn'’’t I cool and stylish?

Hey, do we have time for one more?

- Well, it'’’s getting late, and it'’’s gonna get dark soon.

- Yeah, we should probably head home soon.

- Yeah.

- Aww.

I wish we could keep playing.

- Hey, guys!

I have a great idea.

Well, we don'’’t want to have to stop playing because it'’’s getting late, right?

- Yeah.

- So how about a sleepover?

- A sleepover?

- Oh, that would be amazing!

- Oh, yeah!

A sleepover!

This is so great.

I am so excited.

Yeah!

I just have one question.

What'’’s a sleepover?

- [gasps] You mean you, Splash, the explorer who'’’s been everywhere and then some, has never been to a sleepover?

- No, this would be my first time.

You see, I'’’m not really big on sleeping.

I don'’’t sleep much at all.

I never really have.

- Well, but then what do you do at night?

- Well, at night, when you guys are sleeping, I'’’m still kind of awake.

- But you get to do all sorts of fun things at a sleepover besides sleep.

- Like what?

- Okay.

Let me explain it to you.

You see, when you have a sleepover, you and your friends-- - Uh, that would be us.

- Get to spend all night together telling stories-- - And playing games.

- Yeah, and eating snacks.

- And playing games.

- And telling funny stories.

- And playing-- - Let me guess.

all: Playing games.

- Oh, that'’’s my favorite part.

Oh, also the snacks.

- Yeah.

All that fun until you get really tired and everyone falls asleep.

- Wow.

Well, it sounds great.

I'’’m in.

all: Yay!

- Yeah!

It'’’s gonna be great.

Except for the sleeping part.

Oh.

♪ ♪ Well, I'’’m excited about the games, that'’’s for sure.

- Yeah, Dunk?

- Yeah?

- What'’’s that?

- Oh, it'’’s just my little night-light.

- Oh.

Okay, then.

- Yeah, see, the clusterwink snail glows inside the shell, and that glow helps me sleep better.

It'’’s just my thing.

- Oh.

both: Who knew?

- Huh.

Well, who knows?

Maybe it'’’ll help me sleep.

- Oh, don'’’t worry, best buddy.

Besides, the night is young.

There'’’s lots of fun before the sleep even starts.

- Yeah!

All right, everybody.

It'’’s time for Splash'’’s super sandy sleepover to begin!

- Whoo!

- Whoo-hoo!

- Seaweed!

all: Coral!

- [laughs] Seaweed!

all: Coral!

- Whoa, almost got me.

[laughter] - Okay, okay, I got another one for you.

Okay.

What'’’s the strongest creature in the ocean?

- What?

[laughter] all: Yeah!

all: Yeah!

- Dum-da-da-da!

A walking, talking goopy gob of... Mud!

all: No!

- [yawning] All right, guys.

Hoo!

It'’’s getting late.

I guess we should get some sleep.

- So what do we do if we'’’re not tired yet?

- Hmm.

Oh, I have a little bedtime thing that helps me get ready for sleep.

Maybe it'’’ll work for you.

[gasps] Try it with me.

- Huh.

Okay.

[laughs] - All right.

Let'’’s see here.

Oh.

Okay.

First, I check my night-light.

Check.

- Okay.

[clears throat] Check.

- Great.

Okay.

Now repeat and follow after me.

- Okay.

- The tide is calm, the water'’’s deep, and now I can fall fast asleep.

- Fun!

Okay.

[clears throat] The tide is calm.

The water'’’s deep.

The ocean is the place where the jellyf-- I don'’’t-- what'’’s the rest?

- Perfect.

Or close enough.

[chuckles] Yeah, and usually by now, I'’’m pretty much fast... - Ocean is-- Dunk, I don'’’t know if this is working.

Dunk, I-- Dunk?

Hello?

Dunk, Dunk, Dunk, Dunk, Dunk?

Hello?

- Oh, yeah.

That'’’s just how he sleeps.

Hey.

You know what, Splash?

I bet my way of falling asleep would totally work for you.

Ah.

Is this the perfect way to fall asleep or what?

- I'’’ll go with "or what?"

Bubbles, I just feel itchy and muddy.

- Really?

Because this mud makes me feel relaxed, and I usually just fall asleep and just... - So itchy.

Bubb-- ugh, brother.

- My turn?

- Yeah.

- See?

I can attach my tail to some heavy coral like an anchor, so I won'’’t drift away while I'’’m dreaming.

- Oh.

Well, sounds simple enough.

Let me try to attach my tail here to the coral like an anchor.

Like you.

Oh, this isn'’’t so hard.

Oh!

Okay.

- Isn'’’t this a lovely way to fall asleep?

- Oh, it'’’s lovely, yes.

- Now, let'’’s take some deep cleansing breaths.

- It is not working.

- That always works for me.

- Yes, deep breaths.

- In and out.

- [exhaling loudly] - In and out.

- [exhaling loudly] - Peaceful.

- Oh!

- Quiet.

- Yeah, so peaceful, so quiet.

This is incredibly relaxing, Ripple.

Yes.

Very relaxing.

I am attached to the coral.

I am not attached to the coral.

Okay.

Okay.

Let me just-- you are-- And she'’’s out.

Oh, brother.

How am I gonna fall asleep?

[groans] What is wrong with me?

Why can'’’t I fall asleep like they did?

This is supposed to be a sleepover.

Sleep.

[sighs] I must be doing something wrong.

[gasps] That'’’s it.

There'’’s something wrong with me.

Hey, guys.

Guys.

Guys.

Guys, wake up!

Bubbles!

Ripple!

Dunk!

Oh.

Oh, sorry, Dunk.

- No problem.

- I'’’m so sorry to wake you guys.

I tried and I tried and I just can'’’t do it.

I can'’’t fall asleep.

I'’’m ruining the sleepover.

- Oh, no, no, Splash.

No, you'’’re not.

Not at all.

- Well, now what do we do?

- I don'’’t know.

[gasps] But I know someone who will.

- [snoring] - [whispering] Gush!

Hey, Gush!

Gush, are you awake?

- Aah!

Oh, I must have dozed off there for a second.

[laughs] - Well, now that we'’’re all up, we wanted to see if you could help us with our sleepover.

You see, I tried and tried and tried, but I just couldn'’’t fall asleep like the others.

- Aw, well, here'’’s the good news.

It'’’s not your fault.

- It'’’s not?

- Nope.

It'’’s because you'’’re a yellowback fusilier.

Schooling fish like you don'’’t need as much sleep as the other underwater creatures.

Think back.

Did you ever really sleep that much?

- Well, actually, no.

Not really.

- That'’’s because schooling fish help each other out, so your brains don'’’t need as much time to recharge as fish who don'’’t swim in schools.

- Huh.

Like mine.

Boy, it'’’s missing its recharging right now.

- Yeah, but now that Splash lives here with us in Reeftown, shouldn'’’t he need more sleep now that he'’’s not with his school anymore?

- Yeah, I mean, I tried everything.

I hovered like Dunk, I got muddy like Bubbles, I wrapped around coral like Ripple, but none of those ways just felt right.

- Of course not, '’’cause it'’’s not what'’’s right for you.

You'’’ll know when it'’’s time to rest.

- I will?

- Sure, your brain knows when it needs to rest.

You'’’ll be tired and sleepy when you'’’re ready to be.

- Huh.

But I still ruined the sleepover.

- What?

- No!

- No, you didn'’’t.

- We wanted to have a sleepover '’’cause we wanted to keep playing games with each other and having a good time.

- Huh.

Well, yeah, it was really fun.

Even without the sleeping.

- And boy, did we play some fun games.

- Splash told the funniest jokes.

- Yeah, and he was like-- - [snoring] - Oh.

I guess he does sleep sometimes.
