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 Leviathan.
| Mutation | Multiplier | Income / sec | Gain |
|---|---|---|---|
| None | 1× | $220K | — |
| Silver | 1.25× | $275K | +$55K |
| Bloom | 1.5× | $330K | +$110K |
| Golden | 2× | $440K | +$220K |
| Rainbow | 2.5× | $550K | +$330K |
| Spirit Bloom | 3× | $660K | +$440K |
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 Leviathan
Leviathan hatches from eggs stolen in the Lake biome. That biome needs 900 Speed to enter, and the Swan 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 2.3K before attempting a real run. Work out how long that takes from your current Speed →
Where it sits
Leviathan earns 220 thousand times what the weakest pet in the game does, and ranks #29 of 80 pets with a published income figure. The next pet up is Royal Sphinx at $280K/s. Directly below it is Cosmic Gorilla at $180K/s.
Every size and mutation combination
Two Leviathan 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 $165K/s to $1.3M/s — a factor of 8.
| Size | None | Silver | Bloom | Golden | Rainbow | Spirit Bloom |
|---|---|---|---|---|---|---|
| Tiny0.75× | $165K | $206K | $248K | $330K | $413K | $495K |
| Normal1× | $220K | $275K | $330K | $440K | $550K | $660K |
| Large1.5× | $330K | $413K | $495K | $660K | $825K | $990K |
| Huge2× | $440K | $550K | $660K | $880K | $1.1M | $1.3M |
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 Leviathan pays for things
Income only matters relative to what you are saving for. Running one unmutated Leviathan at default size, and nothing else:
| To bank | Takes | Roughly |
|---|---|---|
| $1M | 4 seconds | instant in practice |
| $1B | 1 hour 15 minutes | inside a day of idle time |
| $1T | 1 month 22 days | long enough that you should be earning elsewhere too |
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 Cosmic pet compared
Rarity is a poor guide to income on its own — the Cosmic band alone spans $220K/s to $12M/s. Here is where Leviathan actually sits among them.
| # | Pet | Found in | Income / sec |
|---|---|---|---|
| 1 | Koi | Cherry Blossom | $12M |
| 2 | Snowy Owl | Cherry Blossom | $7.5M |
| 3 | La Vacca Saturno Saturnita | Cosmic | $2.2M |
| 4 | Bronto | Prehistoric | $1.5M |
| 5 | Triceratops | Prehistoric | $1.2M |
| 6 | Beluga Whale | Abyss Ocean | $850K |
| 7 | Whale Shark | Abyss Ocean | $700K |
| 8 | King Mammoth | Snow | $400K |
| 9 | Royal Sphinx | Desert | $280K |
| 10 | Leviathan — this pet | Lake | $220K |
Leviathan is the weakest Cosmic pet, which usually means it comes from an earlier biome than its rarity suggests. The tier list ranks every pet by income regardless of rarity, which is usually the more useful ordering.
