Three tales of discovery highlight the challenges and fun of growing up. The first story depicts Pongo, a young, mischievous African gorilla who wants to grow up to be brave and clever like his dad. But it’s not until his sister, Whoopsie, is born that Pongo discovers growing up isn’t just about chest-thumping. Secondly, as the first penguin chick to be born this year, it’s Otto's job to look after all the other young penguins. But out in the snow and ice of Antarctica, there’s a lot to learn, and Otto has to discover for himself how to swim, dive, and catch fish before he can teach anyone else. In the third tale, a baby aardvark named Pim wonders what exactly it means to be an aardvark! He decides to find out. He’s disappointed when he discovers that aardvarks can’t climb trees, but as time goes by, Pim realizes there are some advantages to being an aardvark after all.
