Pets

Pets are little critters that follow you around; some pets even do small amounts of damage like the pet bat which is summoned by the Vial of Blood which can be found in chests in a dungeon and caverns. The PC version has a variety of new pets introduced in version 1.2, moving beyond the Pet Bunny, which you can summon with the Carrot (only if you have the Collector's Edition. You can obtain the Carrot by creating a new character.) On the console version there are multiple pets not found in the PC version. The pet summoning items are Vial of Blood, Cabbage, Brain, Petri Dish and Wolf Fang all of which can be found in chests.
