Lupo finds a treasure in his garden, but it belongs to a dragon, which immediately comes to take Lupo into his cave. F&F save both him and the dragon. Prof. Knox is kidnapped and later freed by the children. Lupo is a night watchman in a candy factory and wants to show F&F his workplace - when suddenly Limpy & Stinky appear. Makiki is unhappily in love and the worried mummy does everything to cheer him up and help him (incl. beauty salon!) - Dad and mummy get so involved in this action that it inevitably leads to a catastrophe (in the middle of the supermarket).
