Where this comes from
| First-party | Official description — complete Animal Index and claim rewards. |
| Multi-source | Bloxron animals page — HUD location, income seed table, Gold machine, Aurora event. |
| Our own runs | HUD and hatch clips across MeEnyu / Gry Roblox sessions. |
| Unknown | Reward tier thresholds; whether rare sizes are separate Index rows; full roster count. |
What this gets you: A clean Animal Index workflow — where the button is, when to claim, how animals enter the book, and which mutations are real for AnimalByte.
Where the Index lives

The Index sits on the right-side HUD next to Shop. Open it after new hatches. Reward tiers inside the panel are not published — claim what lights up; do not invent thresholds.
How animals get into the Index
- Steal a guarded egg on the badge ladder (or named/event egg).
- Return to Your Base and hatch (Ready! / Open).
- Pen the animal so it earns cash (held pets do not pay).
- Re-open Index — new species should fill in; claim rewards.
Obtain path = hatch stolen eggs. Not world-pickup. Not Lucky Blocks. Not rebirth resets from the twin game.

Mutations that belong here
| Mutation | Multiplier | How |
|---|---|---|
| Gold | ~4× | Mutation Machine by Coils shop — insert 5 identical pets → wait → claim 1 Gold |
| Purple Aurora | ~2× | Purple-aura eggs during Purple Aurora event; hatches can roll Gold+Aurora |
Do not import: Diamond, Ruby, Emerald, or any GiovaDev mutation ladder.

Separate tracks (do not fold into one tier list)
- Rare sizes
- Mythic eggs
- Secret animals
All three are named in the official AnimalByte loop. Odds and full rosters are TBA — keep them labeled separate from Gold/Aurora.
Verified seed species (early Index)
Chicken, Bunny, Coral Goby, Pufferfish, Goat, Owl, Horse, Cat, Boxfish, Sailfish, Zebra, Bear, Red Dragon, Cobra — income snapshots live in animals-patches.json. Treat figures as footage/account snapshots, not hard base rates.
Session checklist (Index)
- Confirm you are on AnimalByte place
126870639873289(steal/hatch HUD: SHOP + INDEX on the right, PETS + EGGS on the left). - After each hatch, Pen the animal — held pets do not pay; offline cash still needs a Pen slot.
- Open Index, claim anything lit, then either train Jump Power or resume the egg route.
- Bank five identical commons for the Gold machine near the Coils shop when cash allows; during Purple Aurora, hatch aura eggs first for the ~2× roll (Gold+Aurora possible).
- Leave rare sizes, Mythic eggs, and secret animals unlabeled as “tier” until odds exist — Index still tracks ordinary hatches separately.
Wrong-wiki warning
https://jumpforanimals.wiki/ may show Index pages mixed with GiovaDev “55 / 9” branding. Prefer AnimalByte place 126870639873289 + Bloxron AnimalByte hubs. If the page talks rebirth and Lucky Blocks, close it for Index advice.
FAQ — Index and mutations
Where is Index? Right-side HUD next to Shop. Notification badges often appear after steal/hatch.
How do entries fill? Hatch stolen eggs at Your Base (Ready! / Open), Pen the animal, reopen Index. Obtain path is hatch-only — not world-pickup, not Lucky Blocks.
Gold? Mutation Machine by the Coils shop: insert 5 identical pets → wait → claim 1 Gold (~4×).
Purple Aurora? Event eggs with purple aura (~2×). Gold+Aurora rolls are possible. Do not list Diamond, Ruby, or Emerald here.
“55 animals / 9 rarities”? That pitch belongs to the GiovaDev twin. Publish verified AnimalByte rows only; leave unknown species TBA.
Troubleshooting — claim and income
If Index does not update, confirm the hatch finished at Your Base and the animal sits in the Pen. Offline cash shows as $/hour on the plot HUD — empty Pens earn nothing. Index reward tiers remain unpublished; claim lit rewards and move on.
Separate chase tracks
Rare sizes, Mythic eggs, and secret animals are officially named. Keep them out of a single fake rarity table. Fill Index from the Meadow→Celestial steal loop first, then chase live banners.
Hard identity line
AnimalByte place 126870639873289 · steal eggs · hatch · Trails/Coils · Gold + Purple Aurora only · no rebirth / no Lucky Blocks from the twin.
Still unknown
- Do not trust “55 animals / 9 rarities” from GiovaDev-branded pages without AnimalByte client proof.
- Index reward math unpublished.
