Boes goes fishing. A big fish swallows the bait, but Boes can`t get it out of the water. He loses confidence in his physical strength and starts to train. 1st of all he challenges Rambau the gorilla and Phat Elephant to arm wrestle, but fails. Next he tries to lift barbells, but falls on his back. He then takes up weightlifting etc., which becomes a nuisance to the animals in the forest...
