It's a Big Big World features Snook the sloth and his many friends in the World Tree. Their tree house is in the middle of the rain forest. With the help of Madge, an old and wise turtle, he helps everyone to learn about scientific concepts such as metamorphosis, molting and much more. Featuring lively music and "Shadowmation," a process developed by Mitchell Kriegman, creator of Bear in the Big Blue House. Snook is very old, slow, and he sleeps a lot.
