The Wheat Goblin

A small yellow goblin with a beard of wheat stalks and huge long floppy ears that look like leaves on a stalk of wheat. It can shapeshift but will always have a long braided beard or braided hair and it will always have it's ears. It tries to sell or offer freely wheat cakes that, if eaten, will render the victim unable to survive on anything but the wheat cakes or (just barely alive) on normal wheat products. Easy to fight and kill, they are not warriors.

But the wheat cakes will give temporary strength and speed to the Wheat Goblin itself and others who eat it. Foolish warriors will occasionally become willingly addicted to the wheat cakes.
