The Spirit of the Great Harvest Holiday

Legends
The legend speaks of a creature with a really long body and a pumpkin instead of head, it haunts the ones who are not doing fun during the holiday.
The legend says that the spirit of the Great Harvest Holiday sometimes goes in disguise as a grifix during the Great Harvest Holiday and checks if the grifix have fun. The disguise looks like a grifix with a pumpkin on its head. If grifix aren't having fun, it gets mad. To show it that you are having fun, if you see it, you gotta give it sweets. Because of this, the little grifix that carries the bag with sweets when treat or treating wears a pumpkin on its head, pretending to be the pumpkin spirit that demands sweets from the grifix.
 
Think of one of those kids wearing a pumpkin meeting another grifix wearing a pumpkin, even though they should be the only one wearing a pumpkin that night...
 
The idea belongs to kazoowary, the art is made by MysteriousShine but it is provisory, it may be changed later, as well as the story. But after all, every legend is different depending on who speaks it, so is there really a canon version to it?
