Malumclaw is an Antagonist in The Land of Stories: The Wishing Spell.
“However, these wolves were unlike any the twins had ever seen before. They were four times the size of any normal wolf of their world. Their fur was jet-black and matted. Their eyes were red, and their snouts were wide. These wolves were ready to kill at any minute. Without a doubt, the twins had come face-to-face with the Big Bid Wolf Pack.”
The name Malumclaw is probably derived from the Latin adjective Malus/Mala/Malum meaning bad or evil, and the English word claw. However, it is possible that the malum could also be derived from the Latin world for apple, which is also malum, and would represent the Northern Kingdom.
