a sketch of a wendigo
Wendigo is a cryptid from native american folklore. They were once human but after resorting to cannibalism, they become a monster. Although in most media they appear with a zombie-esque body, blue with decay, long clawed arms and a deer skull for a head. Scribblenauts depicts them as dark blue monsters with long horns. It scares most other creatures, but making a creature 'fearless' or 'brave' can allow them to face it without running away, revealing that it is actually quite weak, being able to be destroyed by most monsters.
