All the creatures live together in the Undersea Kingdom, also known as the Tropicana Go! sea. The Undersea Kingdom is like a great big fish bowl but it's much, much bigger than a fishbowl you might have in your house. In fact, it's as big as your house!

Inside, everyone has plenty of room to swim and play and eat and drink (Tropicana Go! - of course). There are even shops there where you can buy healthy snacks and drinks, such as Tropicana Go!

So where exactly is the Undersea Kingdom? Well, nobody really knows. It's under the sea somewhere, but no one has ever found it, although people have tried. So, next time you're on a boat or flying over the sea in an aeroplane, have a look to see if you can see it beneath the waves.
