Coconut the little Dragon
Hiccup
S1 E133:
Mette asks Coconut, Matilda, and Oscar to dispose of rotten Dragonfruits in the compost dumpster - the most disgusting place on Dragon Island. To avoid the terrible task, Coconut, Matilda and Oscar feed the Dragonfruits to the Swallowing Pits instead, unaware of the dangerous consequences: Hiccups that shake the whole Island and put Mini Mo in jeopardy.
