The Eternal Star is a secret Legendary pet in Bubble Gum Simulator. It can be obtained by opening a Mushroom Egg. The chance of hatching it is 1 in 80 million (0.00000125%), or 1 in 40 million (0.0000025%) with the Lucky Chances gamepass.


  • This is the 2nd most powerful pet in the game, only beaten by the Godly Gem, and excluding Sylently's Pet.
    • Although still better in the majority of stats, Shard still beats Eternal Star in Coin stats.
  • This is the best pet in the game that is obtainable in a permanently added egg.
