Trama
Plummy is in a good mood and wants to go rock climbing. Plif and Plops, who arrive later, see this quite differently. After stealing all Plummy's equipment, they make their way to the summit. They do everything they possibly can to stop Plummy coming with them. Only after a daredevil rescue mission, in which Plummy saves Plops' life, can they all enjoy a picnic at the top.
