The Tier 10 Egg is purchasable at the Egg Shop. While it is 50,000,000 coins, inside the egg you will find either a Lava Zebra, Lava Dalmatian, Lava Turtle, Electric Slime, Electric Ghost, Dominus Empyreus, Dominus Messor, or Dominus Frigidus.
Each pet has its own strengths and weaknesses. None of them can be made gold.
- The Dominus' are the rarest out of all the pets in the Tier 10 Egg.
