The Penguin Problem

At the South Pole, Peg and Cat are preparing to watch the ski race at the Animal Winter Games when they spy the Penguins zooming downhill. CRASH! The Penguins keep slamming into obstacles! Peg tries to help by shouting directions: “Go over! Go under! Go in between!” But the Penguins don’t know what over, under, and in between mean. Luckily, Cat points out some directional arrows to follow, and a problem is solved . . . for the moment. Now can anyone figure out how to keep the ice floe the Penguins have landed on from tilting?
