[ Splash ] >> Aha.

It's getting hotter.

Just a few more cyber degrees and my hot tub will be the perfect temperature for maximum relaxation.

>> It looks like that crazy machine is heating up the water!

>> Ninety-seven degrees!

>> Three more degrees and it'll reach 100.

>> Then everyone will be forced to move away!

>> That's not going to happen, Eugene.

We'll stop them.

>> Looks like the water goes up the hill in buckets, then down through a hole in the tank where it gets heated and back down this hose.

>> And into our water!

If we can just clog up that hole... >> Didge, do you have something round?

>> Maybe a ball?

>> We need a bigger one.

>> How about this?

Stop.

You can't leave Mermaidos.

There's so much to love here -- the beautiful plants of Mermaidos Gardens, the gorgeous shells of Mermaidos Town Square, the cooling waters of Mermaidos Falls.

>> Wait, what's that about a cool waterfall?
