Bamboo Surprise

S1, E59: Sailing home from China, the Flake Vikings see a dragon. Rushing to get the mythical creature, they realise the dragon is in fact a costume, worn by the villagers to scare away a real monster that is terrorising them. Village elder, Junjie, believes they're cursed by his son Qi's refusal to learn their traditional ways. Qi is determined to prove there are no such things as monsters.
