|Breed:||Welsh Mountain Pony|
Pumpkin is Amy Wrigglesworth's pet pony.
Pumpkin often gives rides to the children of Greendale, but sometimes Amy lets Pat ride him if any of his vehicles break down.
Sometimes he is so powerful that Amy often uses him for big rescue situations.
He is usually good natured, but their are times when can rather grumpy and stubborn if you does not get what he wants. Like most horses he can be easily frightened, so everyone around him most be careful or he may run off and cause trouble.
He occassionally has a job in giving rides to children.
