Mim is canonically a cubus who can change into both an incubus and a succubus. They are sometimes accompanied by a demon possessed plush goat named Billy (known for bad puns). They used to live at Monster Island until Billy flooded it, so now Mim and Billy both live in an abandoned tower called transmission hq. In that space Mim and billy occupies a room filled with personal objects (such as a pic of Mim’s model mama Froggyloch, and a bear shaped mini fridge).
