Crazy Road Trip!

You are on a trip with your friends: Annie, a chubby vampire girl; Bartholomew, a talking cat (not cat-person); Franklin, an alien; Sarah, a decapitated zombie head; Bill, a skeleton; and Tim, a fairy. You are in The DoomWagon, an rv that is its own pocket dimension (like the Tradis) and can drive underwater and fly. Go anywhere, do anything, recruit anyone. Have. Fun.
