Grumb

A small otherworldly creature that fits in the palm of your hand. The humans of this world hunt grumbs in the spring (prime Grumb season) but only the bravest of adventures venture into the retarded forest (home to all horrific otherworldly beings)

"No son of mine shall venture into the retarded forest"

"If you want safe passage through the retarded forest you must pay me 3 Grumbs"

"Couldn't pay me a Grumb to do that"
