Every baby worm dreams of being a gladiator in the worm arena, where burly worms battle it out to eat sheep, grow, and squish their adversaries. Wormhead is a worm who fights in a worm arena in the official Blizzard scenario map for Warcraft III called Worm War. The worm is fed sheep and pigs from which it produces "segments" which follow it. These segments are covered in spikes. Fire elementals are also kept in the arena which might harm the worm. The worm can eat fire elementals with the help of a special item, and each fire elemental is worth 5 more segments.
