Bugbears..... are Boogey Monsters. Like literally same word origin. Bug and boogey both mean Scary thing. Bear/Monster is known. So a bugbear is just a scary hairy thing in the forest. And a boogey monster is a scary thing in the house/closet/under the bed.

They are.... etymologically, the same creature.

I want to do something with that.
