Mini Minotaur

The Mini Minotaur is a Pet summoned by using Tartar Sauce, which is sometimes found in Iron Crates. If the Mini Minotaur moves too far away from the player, it will spin a battle axe as a makeshift propeller to fly to the player. Its eyes glow in the dark, making it useful at night or in dark areas.

Trivia
