Pets: effects and unlocks

Pets are items that spawn an allied creature that fights or helps for the rest of the run. The free Paws & Claws update (February 2026) added nine; Primal Dread adds three more. Most pets have an unlock challenge tied to a build type, such as equipping six weapons that scale with one stat.

Pet damage follows the stat in brackets: Bonk Dog scales with Melee Damage, Catling Gun with Ranged Damage, Blazemander with Elemental Damage. Bot-O-Mine is a structure and scales with Engineering.

Beast Master

The Beast Master cannot equip weapons. Pet damage also scales with Melee Damage, Ranged Damage, Elemental Damage and Engineering, and every permanent pet gives +2% Speed. It starts with a Lootworm and, since update 1.2, a Ratzilla. The shop favours Pet items.

It unlocks when you have unlocked Bonk Dog, Catling Gun, Bot-O-Mine, Blazemander and Lootworm. Winning with it unlocks Scapegoat.

Pet options

Accessibility options can highlight pets and turrets and change pet transparency, which helps when several pets crowd the screen.

Petting Zoo challenge

Having three pets at the same time unlocks Hungry Hungry Dinosaur. The Beast Master starts with two pets, so one more pet bought in the first shops completes it.
