Good luck! And I'd keep things real generic and classic and/or cartoonish in the case of monsters. You don't want to scare the kids too much and have the parents complain. So load up on creepy crawlies like spiders, snakes, worms. Pictures of the classic black and white horror monsters like Frankenstein & dracula or bright colored illustrations of such. Scarecrows and bedsheet ghosts.
