♪♪ >> Wibbley-wobbley!

I detect a foul odor.

>> Ewww!

>> What is that?

And where is it coming from?

>> Oh, we must find out immediately!

>> Don't worry, Queen Mum.

We're on it.

>> Follow that smell!

[ Sniffing ] Oh!

Found it.

>> Phew!

The smell is definitely coming from this plant!

>> Unfortunately, yes!

>> What is it?

>> Never saw it or partook of its malodorous fragrance before today.

>> We believe it's a weed of some sort.

>> These flowers are wilting.

>> Who could blame them?

It stinks here.

>> Well, if it's just a weed, let's pull it out.

>> Would it be okay to do that?

>> Wasn't here before.

>> Doesn't belong here, so it won't be missed.

>> I can't grow a plant, but pulling one out?

That I can do.

[ Straining ] This is one tough weed!

[ Rumbling ] >> Whoa!

>> [ Gasps ] >> Did that just happen?

>> There was one stinky plant, and now there are two.

Double ew.

>> I'll help.

[ Both straining ] [ Rumbling ] >> Yikes!

There were two stinky plants.

Now there are 1, 2, 3, 4!

Twice as many!

>> The smell doubled, too.

[ Rumbling ] >> Oh, no!

Now there are 1, 2, 3, 4, 5, 6, 7, 8 stinky plants!

>> They doubled again!

>> I didn't touch them that time.

>> They're growing on their own!

>> We need more information.

[ Beeping ] It's called a Funky Flower.

>> What a perfect name!

>> It can only be found in Jungolia.

>> Jungolia?

Anything else?

>> It says if the Funky Flower is planted anywhere other than in Jungolia, it could become...an invasive species?!

>> Oh, no!

Not an invasive species!

It can't be an invasive species!

Wait.

What's an invasive species?

>> A plant that's taken from one place and planted somewhere else but doesn't get along with the plants that are already there.

>> What happens when the plants don't get along?

>> Oh!

This is not good!

This is not good at all!

>> What?

What does it say?

>> If a Funky Flower becomes invasive, it grows quickly, steals water, blocks sunlight, and crowds out other plants.

>> Yoikes!

Gardenia is in trouble.

>> We must save the Queen!

Move out!

[ Creaking ] >> You do realize we're planted in the ground, right?

>> Don't worry.

We'll help.

[ Straining ] [ Rumbling ] >> I hate to say this, guys, but it looks like the Funky Flower has become an invasive species!

>> And it's growing towards the Queen!

>> How close is it?

>> It still has a ways to go.

I'll measure.

It'll take forever to measure with this.

Wait!

The Queen said you can measure with anything.

Those hedges are the same size.

I can use them to measure.

1, 2, 3, 4, 5, 6, 7, 8.

The weeds are eight hedges away from the Queen.

[ Rumbling ] Eh, make that seven.

>> Oh, the Funky Flower is spreading.

>> I guess Gardenia isn't so happy.

>> I guess not.

Soon, it will crowd out all of the plants and flowers, including Queen Mum!

>> But, Boss, if that happens... >> Yes?

>> ...who's going to be the leader of Gardenia?

>> Me, of course!

And with my invasive species doing all the work, those Earthbrats can't stop me!

I'll be king of Gardenia!

Yum.

>> The weeds are six hedges from the Queen.

>> The other plants and flowers are getting pushed out!

>> They have no space to grow!

>> Guys, calm down for a sec.

Let's observe what's happening and see if we can figure out what to do.

[ All scream ] >> Um...we better observe fast!

>> If we could just stop the roots from moving, maybe they'll stop growing.

>> But how?

Aah!

>> When we had a new puppy and didn't want her to run out of the yard, we put a fence around it.

>> A fence!

That's it!

We can use these rocks.

>> All right, Cybersquad.

Let's build a fence!

[ All grunt ] [ All grunt ] ♪♪ >> Done!

[ Rumbling ] >> Uh-oh!

>> We did it!

[ All cheering ] [ Rumbling ] >> Whoa.

What's happening?

W-what are they doing?

>> Hold on.

Seeds!

Aah!

Ooh!

Ow!

Ooh!

Aah!

>> Oh, no!

Now the seeds are growing into plants.

>> Didge!

How close are we to the Queen?

>> The weeds are 1, 2, 3, 4, 5 hedges away...and moving fast.

>> We need a new plan and fast
