The best picture of the witch in game.
This Wicked Witch is a minor antagonist in the Shrek 2 video game. She appears in the level, Spooky Forest, where she turns the onion carriage horses back into mice. In an attempt to eat them, she leaves a trail of cheese leading to a boiling pot. Ultimately failing, she abruptly kidnaps Fiona, which is then foiled by Donkey and Dragon.
In the level, the witch is rarely seen, only being spotted flying through the area at random.
