Werewolf
Even a man who is pure in heart and says his prayers by night may become a wolf when the wolfbane blooms and the autumn moon is bright.
Witch
An evil she-bitch who rides a broom, boils gross stuff, torments the Collins family, and does other stupid evil shit. They are all probably evil, and should all fuck off!
Zombie
A mindless re-animated corpse. Originally voodoo based slaves in 1931's White Zombie, George Romero later solidified their status as infected flesh-eaters in 1968's Night of the Living Dead.
