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 T-Rex.
| Mutation | Multiplier | Income / sec | Gain |
|---|---|---|---|
| None | 1× | $25M | — |
| Silver | 1.25× | $31.3M | +$6.3M |
| Bloom | 1.5× | $37.5M | +$12.5M |
| Golden | 2× | $50M | +$25M |
| Rainbow | 2.5× | $62.5M | +$37.5M |
| Spirit Bloom | 3× | $75M | +$50M |
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 T-Rex
T-Rex hatches from eggs stolen in the Prehistoric biome. That biome needs 17M Speed to enter, and the T-Rex 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 42.5M before attempting a real run. Work out how long that takes from your current Speed →
Where it sits
T-Rex earns 25.0 million times what the weakest pet in the game does, and ranks #14 of 80 pets with a published income figure. The next pet up is Tralaledon at $32M/s. Directly below it is Kraken at $15M/s.
Every size and mutation combination
Two T-Rex 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 $18.8M/s to $150M/s — a factor of 8.
| Size | None | Silver | Bloom | Golden | Rainbow | Spirit Bloom |
|---|---|---|---|---|---|---|
| Tiny0.75× | $18.8M | $23.4M | $28.1M | $37.5M | $46.9M | $56.3M |
| Normal1× | $25M | $31.3M | $37.5M | $50M | $62.5M | $75M |
| Large1.5× | $37.5M | $46.9M | $56.3M | $75M | $93.8M | $113M |
| Huge2× | $50M | $62.5M | $75M | $100M | $125M | $150M |
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 T-Rex pays for things
Income only matters relative to what you are saving for. Running one unmutated T-Rex at default size, and nothing else:
| To bank | Takes | Roughly |
|---|---|---|
| $1B | 40 seconds | instant in practice |
| $1T | 11 hours 6 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 T-Rex actually sits among them.
| # | Pet | Found in | Income / sec |
|---|---|---|---|
| 1 | Stag | Cherry Blossom | $145M |
| 2 | Cosmic Dragon | Cosmic | $60M |
| 3 | Cosmic Skeleton Boss | Cosmic | $45M |
| 4 | Tralaledon | Prehistoric | $32M |
| 5 | T-Rex — this pet | Prehistoric | $25M |
| 6 | Kraken | Abyss Ocean | $15M |
| 7 | Cerberus | Volcano | $8M |
| 8 | Yeti | Snow | $5M |
| 9 | King Snake | Jungle | $3.5M |
T-Rex sits 5 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.
