The wiki first listed the Extinction Egg pets on Sep 27, 2026. Those are wiki page dates, not the game's patch notes.

How to get Extinction Egg pets

Extinction Egg pets come from the Extinction Egg, not from a zone, so there is no Speed requirement and no nest to camp. The wiki gives no spawn chance for any of them, so we cannot say how many eggs one takes.

Sources like this come and go with the weekly Saturday updates, and the wiki does not mark which are still open. The updates page shows what is live now and the countdown to the next update.

Are Extinction Egg pets worth it?

The wiki gives no spawn chances here, so there is no "average egg" to compute; the values are what each pet earns at base size. No zone's average egg matches Sabertooth.

Measured against the zone ladder: Sabertooth ($5B/s) is first out-earned by a zone pet in Angels & Demons, where Aetheron makes $6.9B/s; Glyptodon ($22.5K/s) is first out-earned by a zone pet in Lake, where Leviathan makes $220K/s.

Size and mutations change all of this: a Rainbow Sabertooth earns $17.5B/s at base size, and a bigger one more still. The income calculator does the arithmetic for any weight.

Extinction Egg pets against the zone ladder

For each pet: the first zone whose average egg is worth as much, and the first zone whose best pet earns as much. "None" means no zone reaches it.

What Extinction Egg pets earn per hour and per day

Base income per second, minute, hour and day for every Extinction Egg pet with a listed value, at base size with no mutation. Size changes it: Sabertooth at ten times its base weight (600,000 kg) earns $20.7B/s, Glyptodon at ten times its base weight (30,000 kg) earns $93.1K/s.
