Sally and Nick are playing up in their tree house when Nick's mom calls them in for lunch. Nick wonders what it would be like to stay up in that tree all the time! The Cat in the Hat knows! Or at least he has friends that do. In the Jimmer-Jammer Jungle the kids learn how different animals spend their entire lives in trees. As neat as that is, there's one thing those trees don't have, and that's mom's home cooking!
