Bike For Egg Pet Rarities – Secret, Eternal and Divine

What pet rarities exist in Bike For Egg?

Pets roll with a rarity label, and the top of the ladder is confirmed to include Secret, Eternal and Divine. Divine sits at the top, above Eternal and Secret.

Rarity is not cosmetic. A higher-rarity pet generally earns more Money per second than a lower one, which is why hunting better eggs is the core progression loop. Lower-rarity pets still matter as fusion material and as early income.

The game does not publish a complete rarity chart, so this wiki lists only the labels it can confirm. This wiki also does not list a per-egg pet pool without an official source, since drop pools can change with updates.

Does size matter?

Yes. Every pet has a weight-based size, and a heavier pet of the same species earns more than a smaller one. That is the entire point of the Fuse Lab: three matching pets go in, and one heavier egg of the same species comes out.

Size is separate from rarity, so compare a pet’s actual income and weight before replacing it. The rarity label alone does not tell the whole story.

How do mutations work?

Mutations are bonus modifiers that raise a pet’s value. A mutated pet earns more than the same pet without the mutation, and mutations can appear on hatched pets.

The important rule is at the Fuse Lab: if any of the three pets you submit carries a mutation, the best mutation among them transfers to the resulting egg. That makes mutated duplicates valuable as fusion material rather than something to sell.

Why are there no exact hatch odds?

Bike For Egg does not display hatch percentages in-game, and the developer has not published a drop-rate table. That means any precise “0.01% Divine” figure you see is either an estimate or invented.

What can be verified:

• Rarity labels exist and are visible on pets.
• Higher rarities generally earn more.
• Size and mutations change income.
• The Animal Index tracks the pets you have collected.

If a drop-rate table is ever published officially, this page will be updated with it and the source named. Until then, the honest answer is that the odds are unknown.

What is the Animal Index?

The Animal Index is the game’s collection tracker. It records the pets you have hatched, and the official game description says completing it grants rewards. The developer has not published the exact reward table, so this wiki does not list reward values.

Use the Index to spot missing species before you sell a duplicate. A pet that is weak for income can still be worth keeping if it fills an empty Index entry.

How should you use rarity when playing?

Early on, keep the highest-earning pets in your base and fuse or sell the rest. Rarity is a shortcut for judging a pet, not the whole story: check its income number and its size before deciding.

• Keep your best earners active at base.
• Fuse matching duplicates instead of selling them for small cash.
• Do not sell a mutated pet just because it is low rarity; it may be better fusion material.
• Save rare eggs for a session where you can hatch several at once.
