Glyptodon guide
The Extinction Egg is the paid egg that arrived with Update 6, and Glyptodon is its humble end: a Legendary at $22.5K/s that shares the egg with Sabertooth, a Divine making $5B/s.
What the Extinction Egg does
Update 6 describes the Extinction Egg as a new paid egg with 6 extinct animals. Each hatch has a small chance to re-roll, and a re-roll gives a rare Skeletal version of the animal. For Glyptodon that version is Skeletal Glyptodon, a Secret worth $550M/s, roughly 24,000 times the plain pet. The wiki doesn't state the re-roll odds.
Because it is a paid egg, there's no biome, Speed requirement or guardian involved. The same update also brought Dr. Scramble's Laboratory, but that is a separate system with its own banners.
The $2.2M hatch reward
Glyptodon is one of the few special-egg pets with a documented hatch reward: $2.2M in cash, with no Speed listed. For a pet that earns $22.5K/s, that payout equals roughly 98 seconds of its own income, a small bonus on the way to whatever you hatch next. The wiki doesn't record a grow time.
Income and estimates
- 7th of 21 Legendary pets; 148 of 198 pets earn more.
- Base weight: 3,000 kg, heavy for its rarity.
With the formula the wiki documents:
- Golden: about $56.2K/s
- Rainbow: about $78.8K/s
- 10x base weight: about $93.1K/s
- 100x base weight: about $385K/s
- Rainbow at 100x weight: about $1.35M/s
Plain Glyptodon is the outcome you'd least want from an Extinction Egg, but it's still a documented step toward completing the extinct set and, with luck, its Skeletal form.
