Income with documented mutation multipliers
Show Cosmic Gecko's calculated mutation rates
Reported base × documented mutation factor; size held at 1×. These are projections, not separate measured variants.
| Mutation | Multiplier | Income / sec | Gain |
|---|---|---|---|
| None | 1× | $30K | — |
| Silver | 1.25× | $37.5K | +$7.5K |
| Bloom | 1.5× | $45K | +$15K |
| Golden | 2× | $60K | +$30K |
| Rainbow | 2.5× | $75K | +$45K |
| Spirit Bloom | 3× | $90K | +$60K |
Only mutations with a retained numerical multiplier are modeled; this is not every mutation available in the game. Size can change the result. The income calculator combines the modeled inputs.
How to get Cosmic Gecko
Cosmic Gecko hatches from eggs stolen in the Cosmic biome. That biome needs 700M Speed to enter, and the Dragon patrols it.
The listed entry figure does not establish a safe carrying speed. Check the entrance and your return route; we have not measured a universal safety margin. Plan a target using your actual training rate →
Its egg sits in the ordinary Cosmic nests, which refill at every egg reset — get it home before the Dragon catches you. How egg spawns work → The published rarity-wide hatch band is a few minutes; it is not an individually timed Cosmic Gecko result. Use the duration shown on your egg. Track it →

Listed references support this record. This is desk research, not a fresh in-game test; exceptions are noted below.
Where it sits
Cosmic Gecko ranks #37 of 80 numerical entries in our current dataset. Provisional figures are included; pets with unknown income are excluded. This is not a complete game-wide ranking. The next pet up is Sabertooth Tiger at $35K/s. Directly below it is Tiger at $28K/s.
Compare your actual size and variant
Use Cosmic Gecko's displayed earnings for a real budget. The income calculatorcompares your line-up; the size guide explains why an assumed size factor cannot prove a pet's actual income.
Saving-time projections for Cosmic Gecko
Time = savings target ÷ reported base income. This assumes one unmutated Cosmic Gecko, constant earnings and no spending or interruption:
| To bank | Takes | Calculation scope |
|---|---|---|
| $1M | 33 seconds | Constant-rate projection |
| $1B | 9 hours 15 minutes | Constant-rate projection |
| $1T | 1 year 20 days | Constant-rate projection |
These projections do not validate offline limits, collection caps or server bonuses. To combine pets you already own, run your own line-up.
Listed Legendary pets compared
Rarity is a poor guide to income on its own — the Legendary band alone spans $1.8K/s to $74K/s. Here is where Cosmic Gecko actually sits among them.
