Brain

The Brain is a pet-summoning item that spawns a Pet Zombie when used. It grants the Pet Zombie buff that lasts until the player manually cancels it, or dies. The Pet Zombie deals 6-7 damage when it touches an enemy, critter, or another player in PvP.

It is a common drop from The Groom. It can also rarely be obtained from Gold Chests, Lihzahrd Chests, and Shadow Chests.

Trivia

 * It deals the second most damage out of the pets on the Console version, only behind the Pet Werewolf.
 * The animation of the zombie when you fly has the same look as the Spectre Boots animation while flying.
 * The pet Zombie is one of 5 exclusive pets that deals quick damage to enemies, critters, and other players (when PvP is enabled).
 * Despite being a brain, the Brain of Cthulhu does not drop the Brain.
