Ride A Pet Index Guide: Pets, Eggs, and Mutations

What are the three Index tabs?

The September 16 player screenshots show the Index as a registry with Pets, Eggs and Mutations tabs. Use those examples to recognize the interface; the later official events mean this is not a complete current roster. The official description confirms the egg/pet/mutation loop but does not publish every Index rule.

How does registration work?

To check a discovery, open the actual entry before the pickup/hatch, note its state, perform the relevant action and reopen it. An entry changing from hidden to named is observable credit. Do not assume that summoning, buying, seeing and hatching are interchangeable triggers for every tab.

Before selling a pet or rebirthing, check its entry, task requirement and the current retention/reset prompt. This page has not tested permanent registration across every later reset or update. A slow pet can still be needed by a requirement; use the pet reference rather than selling purely by rarity.

For a reward, read the current Claim value and compare the balance/result afterward. The archived $15K at eight discoveries observation is one milestone, not proof that every session pays it or that rewards scale by a known formula. If credit or a claim fails, record the entry name, before/after state and actual message for the creator.

How do I read the Pets tab odds ladder?

The September reference contains visible names from Snail (1 in 2) through Kangaroo (1 in 3K), with further silhouettes. Those numbers are the displayed reference; an unnamed silhouette is not evidence for a pet name, and a global 1-in-N entry does not identify the exact current egg pool.

For the Fox, distinguish the dated paid card from the reported free route. For a probability actually displayed in your client, use the custom odds calculator. Do not convert clover/luck directly into a pet percentage without a verified formula.

What the Eggs and Mutations tabs tell you

• Eggs: use the observed labels alongside the dated map and egg route. A candidate landmark is useful even when the egg is absent; its absence does not establish why it is absent or a fixed countdown.
• Mutations: compare your pet’s actual displayed income/speed before and after. The mutation reference preserves September values, not a fresh guarantee for every new event.
