Expected value: not computed for this egg. Reason: not every hatch chance is published for this egg. An expected value built on a guessed chance or an unpriced pet would be a made up number, so this page leaves it out until the inputs exist.

Chances are the figures the Pet Simulator Wiki publishes. Where the wiki prints no chance for a pet, this page says Not published rather than splitting a tier figure. RAP figures are the Normal variant's recorded sales average from the official feed.
Values and exists counts: the official BIG Games public API (ps99.biggamesapi.io), pulled November 1, 2026, 16:42 UTC. RAP is a recorded average of real Trading Plaza and auction sales, not a guaranteed trade price.
