The Mischief Maker - World of Warcraft item

Use: Transforms a friendly target into a sheep, forcing it to wander around for up to 15 sec. While wandering, the sheep cannot attack or cast spells but will regenerate very quickly. Any damage will transform the target back into its normal form. Only one target can be polymorphed at a time. Only works on Beasts, Humanoids and Critters, and only in Dalaran.
