Pets

Unlocking Method
Pets can be found by opening Reality Collisions found in Caves in Awakened Mode. These resemble square, fragmented piles of rocks glowing with a strange green energy. Upon being smashed opened, they will drop a random Pet, which will then be available for purchase in the Catalog for a sum of Gold. All Pets are unlocked by this method. Every Pet has the exact same chance to be unlocked, regardless if any players already have specific ones unlocked. Note that only the host of the lobby is able to see Reality Collisions, though they can be broken by anyone. Upon being opened, everyone currently in the lobby will have the Pet available in the Catalog. It is possible to get duplicate Pets, in which case they will not appear in the Catalog if they have already been unlocked. There are currently 22 different pets to collect.

Purpose
Currently, Pets do not serve any function and will simply follow their owner around. While doing so they drop little particle effects, the type fitting in with what pet they are. Regardless, they are purely collectable, cosmetic items.

Some Pet descriptions are currently missing from this table.

List of Pets
Note that while the Frobbit, Slime Ghost, and Snow Sprite were all added during seasonal Events, they are not season specific and can be found during any time of the year, regardless if an Event is ongoing or not.

Trivia

 * Some pets feature similar looks to many Alternate Dimensions, suggesting that they may have originated from there.
