List of Biomes (Pet Simulator X)

Biomes, also known as areas, are differently themed parts of each world. Biomes cost one of five currencies of Coins, Fantasy Coins, Tech Coins, Rainbow Coins and Cartoon Coins to unlock. Diamonds can be spent to unlock teleporting to any of the biomes or buy 3 sub-biomes in Spawn World, Tech World, and Pixel World.

Unlocking some biomes allows the player to access new eggs, resources and machines.
