Steal An Egg Index: Discovery Rewards and Collection Weapons
Find the difference between one-pet discovery claims and complete-biome weapon rewards, with dated collection mappings.
After discovering a species, inspect its claimable Speed and money reward. Completing a world collection is a separate objective: the captured eleven-world Index uses eight distinct species per world.
Claim a discovery without confusing it with completion
- Open Index using its blue button below Shop in the captured layout.
- Locate the newly discovered species and inspect the claim state.
- Claim the displayed reward if it is available.
- For a world weapon, collect all eight distinct entries in that world and check 8/8.

A duplicate of a species does not fill a missing distinct entry. A larger or mutated version is a different pet instance, but the captured completion counter tracks species. Use the missing names in the pool table to plan a collection route.
Keep special collections separate
The Wiki distinguishes the eleven world collections from Monster Egg and Brainrot Egg collections. A matching reward icon does not by itself establish an unlock rule. Do not add Rift or later event records to an old world’s eight-entry requirement.
Common questions
Will hatching the same species again complete a missing Index entry?
The captured world collection counts distinct species, so extra copies do not replace a missing name.
