A Pet's function is to act as a companion. Having a Pet grants you bonus Damage and bonus Gold you can obtain from defeating enemies.

You also gain the ability to unlock an extra offer in the shop through which you can purchase bonus gems. When purchasing a gem pack while a Pet is activated, you can get a certain amount of extra gems if you use a higher amount of Nutaku Gold.

Pets can be accessed from the Shop menu by selecting the Pet button, which is the last on the list.
