(Splashing) And look at them stop, stop, stop!

Oh, no.

I wonder what stopped the water this time.

Is there another hole?

Hmm, I don't see one.

The water stays in the slide when it's going down.

But right where the slide curves up, the water flows over the edges and down onto the ground.

Maybe it's easier for the water to go down than it is to go up.

So, instead of going up the slide, it spills down over the edge.

So, if we want the water to stay on the slide all the way to the bottom... We have to make sure the slide is always going down.

Aha!

That's what those levers are for.

You're right, Fish!

Let's go fix this slide!

You have to remove that one.

Ooh, that worked.

Now, bring the straight one up.

Ooh, a little bit this way.

Almost got it.

Perfect!

You did it!

Now, the slide goes all the way down.

And the water should, too!

Okay, Things!

Turn on the tap, please!

THINGS: Uh-huh!

Now, that's what I call a waterslide!

(Cheering) (Laughing, chattering) It works!

What do you think, Cat?

I think it's time to go with the flow!

Okay, Nick, are you ready to whoosh and whirl?

I'm way ahead of you, Sally!

Whoo-hoo!

Here I come!

Let's take the plunge.

Ooh, I'm not sure about this.

It's only water!

(Both shouting) (All shouting, cheering) Yippee!

Yeah!

(Cheering)
