Father takes Pingu and Pinga to the swimming pool. While they’re getting ready to go in, they see a penguin dive into the deep pool from the top of the diving block, which worries Pingu. Father then jumps into the shallow pool, as does Pinga, but Pingu gets in by sliding in from a sitting position. Pingi, Pingo and Pingg arrive and have a good laugh at Pingu in the shallow pool, and challenge him to come over to the big pool and jump in. Pingu goes off with them, and they climb to a ledge halfway up the diving block. Pingo and Pingg jump straight in, but Pingu shows off to Pingi and climbs a bit higher. He goes to jump in but once he sees the height he can’t, and climbs back down to Pingi. By now Pingo and Pingg have climbed back up, have a laugh at Pingu and jump in again. Pingi also jumps in. Pingu decides he’s not to be outdone, so he climbs right to the top and stands on the edge. With Pingo, Pingg and Pingi urging him on, Pingu gathers his courage and jumps, but changes his mind at the last minute and just manages to grab hold of the edge of the diving block before he falls, thinking it might be frozen solid. Father and Pinga come over as Pingu hangs precariously over the water, and Father shouts instructions to Pingu. Pingu tries to climb back but slips, and falls head first into the pool with a big splash. When he climbs out Pingu is congratulated by the others, but is a bit shocked by the experience. He then gets his courage back and dives in properly from the lower ledge, and is cheered by the others.
