Income with every mutation
Mutations multiply base income, so the same mutation is worth wildly different amounts on different pets. Here is what each one is actually worth on Cosmic Dragon.
| Mutation | Multiplier | Income / sec | Gain |
|---|---|---|---|
| None | 1× | $60M | — |
| Silver | 1.25× | $75M | +$15M |
| Bloom | 1.5× | $90M | +$30M |
| Golden | 2× | $120M | +$60M |
| Rainbow | 2.5× | $150M | +$90M |
| Spirit Bloom | 3× | $180M | +$120M |
Size stacks on top of these. Full mutation sourcing is on the mutations page, and the income calculator lets you combine both.
How to get Cosmic Dragon
Cosmic Dragon hatches from eggs stolen in the Cosmic biome. That biome needs 700M Speed to enter, and the Dragon patrols it.
The listed requirement is an entry floor, not a safe margin. Guardians chase, and carrying a large egg slows you down on the way home, so aim for roughly 1.8B before attempting a real run. Work out how long that takes from your current Speed →
Where it sits
Cosmic Dragon earns 60.0 million times what the weakest pet in the game does, and ranks #11 of 80 pets with a published income figure. The next pet up is Ice Dragon at $65M/s. Directly below it is Cosmic Skeleton Boss at $45M/s.
Every size and mutation combination
Two Cosmic Dragon are almost never worth the same amount. Size and mutation stack, so the spread between the worst and best version of this one pet runs from $45M/s to $360M/s — a factor of 8.
| Size | None | Silver | Bloom | Golden | Rainbow | Spirit Bloom |
|---|---|---|---|---|---|---|
| Tiny0.75× | $45M | $56.3M | $67.5M | $90M | $113M | $135M |
| Normal1× | $60M | $75M | $90M | $120M | $150M | $180M |
| Large1.5× | $90M | $113M | $135M | $180M | $225M | $270M |
| Huge2× | $120M | $150M | $180M | $240M | $300M | $360M |
Mutation multipliers are sourced and listed on the mutations page. The size multipliers are approximations — the game confirms larger pets earn more but does not publish the curve, so treat the size axis as a comparison aid rather than exact figures. This is the same caveat that applies everywhere on this site: where we are estimating, we say so.
How fast Cosmic Dragon pays for things
Income only matters relative to what you are saving for. Running one unmutated Cosmic Dragon at default size, and nothing else:
| To bank | Takes | Roughly |
|---|---|---|
| $1B | 16 seconds | instant in practice |
| $1T | 4 hours 37 minutes | inside a day of idle time |
Pets earn while you are offline, so these are wall-clock times rather than play time. A full pen multiplies them down — put your actual line-up into the income calculator for the real figure.
Every Secret pet compared
Rarity is a poor guide to income on its own — the Secret band alone spans $3.5M/s to $145M/s. Here is where Cosmic Dragon actually sits among them.
| # | Pet | Found in | Income / sec |
|---|---|---|---|
| 1 | Stag | Cherry Blossom | $145M |
| 2 | Cosmic Dragon — this pet | Cosmic | $60M |
| 3 | Cosmic Skeleton Boss | Cosmic | $45M |
| 4 | Tralaledon | Prehistoric | $32M |
| 5 | T-Rex | Prehistoric | $25M |
| 6 | Kraken | Abyss Ocean | $15M |
| 7 | Cerberus | Volcano | $8M |
| 8 | Yeti | Snow | $5M |
| 9 | King Snake | Jungle | $3.5M |
Cosmic Dragon sits 2 of 9 in this band — $145M/s separates the top of the tier from the bottom. The tier list ranks every pet by income regardless of rarity, which is usually the more useful ordering.
