Recently a mysterious creature has been flying over the island at night, terrifying the inhabitants. Is it a dragon or a giant bat? Only Black Cat remains calm saying that he has known the creature for a long time and if everyone brings it something good to eat, it will surely go away. The islanders follow this advice but Mumfie suspects a trick...

Mr. Bernard has just lent his hot-air balloon to Pinkey and Jelly Bean who decide to go for a flight. Not wishing to upset them, Mumfie agrees to go too but does not dare to admit that he is scared of heights. Will he be able to overcome his fear when he has to save his friends?
