Pumpkin dragons are a very small breed, named after their affinity for pumpkins. They are always found living inside hollowed-out pumpkins, and are only seen during the harvest season. Young children often hollow out and decorate their pumpkins in the hope that a Pumpkin dragon will make it his or her home.
With the (mistaken) idea that due to their small size, the Pumpkin dragons would like to sleep together in a pile like dogs, raindear carefully grew a giant pumpkin for them. To please raindear, they use the giant pumpkin when she visits the Rainbow Cavern, but when she leaves, they breathe a collective sigh of relief, and return to their own sleeping pumpkins.
