Penguin and his rambunctious young friends are off to the playground, running so fast that they knock each other down. Is that right? No, that's wrong! They should walk so that no one gets hurt. At the seesaw and slide, the silly mishaps continue, with pals like Elephant and Chimpanzee playing dangerously (in funny ways), then safely. Hippo bounces a ball off of Penguin's head (BOINK!), and Rhino throws sand in Lion's fur. But by the end of the day, the friends have learned the rights and wrongs of playground play, and they even pick up their toys before heading home!
