Earn 28 Stars, buy the Gemstone Egg, and chase the 0.05% hatch that unlocks this royal purple penguin.

The Amethyst Penguin is a Legendary pet added to Adopt Me on September 11, 2026, as part of the Star Rewards revamp. It is a chubby, pastel-purple penguin with dark eye markings, an ornate gold-and-magenta jeweled tiara, and a matching high-collared royal cape. There is only one way to hatch it, and the odds are steep.

Quick answer: Collect 28 Stars through daily logins, buy the Gemstone Egg from Star Rewards, and hatch it. Each egg has a 0.05% chance of producing the Amethyst Penguin.

How to get the Amethyst Penguin in Adopt Me

The Amethyst Penguin only comes from the Gemstone Egg, and that egg is locked behind the Star Rewards system. You earn its currency by logging in, then spend it in the Star Rewards shop.

Log into Adopt Me regularly to build up Stars. The Star Rewards track hands out currency for consistent daily logins, so the count grows the more days you play.
Once you have 28 Stars, open the Star Rewards shop and purchase the Gemstone Egg. It is a Legendary-tier egg and the only container that can hatch the Amethyst Penguin.
Hatch the Gemstone Egg. Every hatch rolls independently against the pet pool, so a single egg is unlikely to give you the penguin on its own.

You can also acquire an Amethyst Penguin through trading with other players if you would rather skip the hatching gamble entirely.

Gemstone Egg hatch odds

The Gemstone Egg can hatch eleven pets in total, split across Ultra-Rare and Legendary tiers. The Amethyst Penguin sits at the bottom of the probability chart, making it the rarest possible result.

OutcomeRarityChance per hatch
Amethyst PenguinLegendary0.05%
Other LegendariesLegendary9.95%
Ultra-Rare petsUltra-Rare90%

The other Legendaries in the pool include the Diamond Dragon, Diamond Griffin, Golden Dragon, Golden Griffin, and Golden Unicorn. The Ultra-Rare tier covers the Ginger Cat, Orca, Pomeranian, Starfish, and Toucan.

Because the penguin is exclusive to this egg, saving your Stars for Gemstone Eggs rather than smaller shop boosts gives you the most attempts at it.


Amethyst Penguin growth tricks

Like every Adopt Me pet, the Amethyst Penguin learns a new trick as it ages through each growth stage. Here is the order in which they unlock.

Neon and Mega Neon versions

Collecting multiple Amethyst Penguins lets you combine them into Neon and, eventually, Mega Neon forms. Both variants exist in the game’s crafting path, though no unique Neon or Mega Neon appearance for this pet has been shown yet.


How to confirm you got it

When a Gemstone Egg hatches into the Amethyst Penguin, the pet appears in your inventory tagged as Legendary, showing the pastel-purple penguin in its jeweled tiara and royal cape. If the egg produces any other pet, it did not roll the penguin, and you will need another Gemstone Egg to try again. From there, you can grow it through its trick stages or list it for trade with other players.
