| Mutation | Income × | How to obtain / chance | Visual effect |
|---|---|---|---|
 Nitro | ×2.75 | Buy Nitro Mutation in the race shop for 475 trophies earned in Nitro Race. Successful application gives ×2.75 income. The consumable has a 10% application chance; buying it does not guarantee the mutation. | Not provided |
 Enchanted | ×2.85 | Craft Enchanted Essence at the Enchanted Mutation Shrine inside the tree: 240 Emerald, 115 Sapphire, 40 Amethyst and 1 Radiant Butterfly. Apply it to an unhatched egg; application succeeds 100% of the time. | Not provided |
 Scrambled | ×2.75 | Dr. Scramble’s Experiment Shop: 475 Samples; 10% per attempt on an unhatched egg. Genética Gamer checked the in-game notice announcing removal of the consumable that applies the Scrambled mutation, associated with Dr. Scramble. This concerns the consumable; it does not confirm that already-mutated pets will lose their mutation. Our mutation section still lists Scrambled with its ×2.75 multiplier.

 Rainbow | ×3.5 | Normal hatch: 1%. | Continuously changing colors. |
 Parasite | ×3 | Parasite Eggs from the Hungry Frog event; not a normal hatch roll. | A parasite attached to the pet. |
 Fractured | ×2.75 | Rift Boss Shop consumable: 10%; also reported in Boss Mastery rewards. | Cracked appearance. |
 Golden | ×2.5 | Normal hatch: 4%. | Golden shine and coins. |
 Bloom | ×1.25 | Sakura Incubator / Admin Abuse events; check availability in your server. | Cherry blossom petals. |
 Silver | ×1.2 | Normal hatch: 6%. | Silver shine. |
Combining multiple mutations
Add only each mutation’s bonus above ×1. Golden + Rainbow gives ×5; multiplying ×2.5 by ×3.5 would give an incorrect result.
Mutation multiplier = 1 + sum of bonuses above 1
| Combination | Income × |
|---|---|
| Silver + Golden | ×2.7 |
| Golden + Rainbow | ×5 |
| Golden + Parasite | ×4.5 |
Pet size and income table
Compare a pet’s actual weight with its species reference weight. More weight increases income, but not proportionally. Mutations do not change this conversion.
| Weight ÷ reference weight | Size income multiplier | Example: $100/s base income |
|---|---|---|
| ×1 | ×1 | $100/s |
| ×2 | ×1.53 | $153.33/s |
| ×5 | ×2.7 | $269.79/s |
| ×10 | ×4.14 | $413.68/s |
| ×25 | ×7.28 | $727.89/s |
| ×50 | ×11.16 | $1116.09/s |
| ×100 | ×17.11 | $1711.33/s |
| ×125 | ×19.64 | $1963.79/s |
| ×200 | ×23.7 | $2369.97/s |
| ×500 | ×34.19 | $3419.15/s |
| ×1000 | ×45.12 | $4511.6/s |
Hypothetical example without mutations or other bonuses. Table values are rounded. This does not assign one reference weight to every pet.
Use the pet’s weight and the reference for the same species. Do not mix species weights; the displayed weight may also be rounded.
How size is calculated
Up to 125 times the reference weight, the factor is (weight ÷ reference)^(37/60). Above that, growth slows down.
Scale = ∛(weight ÷ reference)
Scale ≤ 5: factor = Scale^1.85
Scale > 5: factor = 19.637875755794113 × (Scale ÷ 5)^1.2
Weight and mutation together
A pet with $100/s base income, 10 times its reference weight and Golden (×2.5) earns approximately $1,034/s. Calculate with the full factor before rounding.
Estimated income = base income × size factor × mutation factor
