Pets

Pets are items that boost you're recharge rate, coin multiplier, and XP multiplier

Pets are obtainable through the Eggs found around each Zone, and cost a certain amount of coins to buy one Egg. Each Egg has a chance of dropping one Pet of any type in the displayed sign next to it, with their varying percentage chances also displayed on the sign.

Pets can be upgraded by giving them XP potions from the Pet Scientist in Zone 2. The potion you give your Pet must correspond to the rarity of your Pet (eg. Legendary Pets must get Legendary XP Potions) When a Pet levels up, it will gain higher coin multiplier and XP multipliers than it's lower level, but recharge rate stays the same.

If you want to evolve your pet and you have the correct potion, click on the pet and there should be an option to evolve your pet.
