As each new update is added to Pet Simulator X, the list of rare pets and the scroll bar inside the experience seem to do nothing but grow. From Golden, Rainbow, and then Dark Matter—pet variations are a rarity in their own right on top of the pre-existing rarity level system. In this list, we’ll be going over some of the rarest pets in Pet Simulator X and explaining how you can, or used to be able to, obtain them.

Rarest Pet

Out of all of the pets in Pet Simulator X, the rarest one is the Blue BIG Maskot pet due to its expensive requirements. To receive this pet, players need to dress their Roblox avatar to reflect the style of Pet Simulator X developer BuildIntoGames. This may not seem like a hefty request until it’s mentioned that the headband that the developer wears will cost you around $500 worth of Robux to obtain.

Though this pet is adorable, and everyone loves a collectible, few players have the Blue BIG Maskot pet, or even blink an eye at it, because of the above pricey conditions.
