First things to do when you start
StepThe game gives you animals to work with from the start. Your first goal is to get a hybrid earning money for you, then build from there.
- Place an animal in the pen money starts accumulating on its own once a hybrid is in there.
- Pick two different animals and fuse them this creates your first hybrid, which replaces the two originals in your pen.
- Put the hybrid on the treadmill training it raises its level.
How fusing works
SummaryFusion is the core mechanic of the game. Choose two animals from your pen, combine them, and a hybrid appears in their place. The two animals you used no longer exist after the fusion completes.
- Rule you must use two different species; two of the same animal cannot be fused.
- Order it does not matter which animal you select first; Ant and Owl in either order produce the same hybrid.
- Result the hybrid is added to your pen and starts earning money automatically.
- Loss the two animals used in the fusion are consumed and removed from your pen.
- Progression fusing hybrids with other animals or hybrids produces even more unusual combinations.

Zones in the Wild
CheckThe Wild is a separate area where you battle encounters to rescue new animals. There are three zones: Grasslands, Desert, and Jungle. Clearing Grasslands and Desert lets you rescue new parent animals to use in fusions.
- Use rescued animals in fusions to unlock combinations that were not possible before.
- Rarer animals produce more distinctive hybrid outcomes, so keep pushing into new zones over time.
Making money faster
TipsThe money your pen generates depends on which hybrids are in it and how efficiently they earn. Level and dollars-per-second ($/s) are separate numbers — a higher level does not always mean a higher $/s, so use $/s as your main measure when deciding which hybrids to keep active.
- Train a hybrid on the treadmill before placing it in the pen.
- Upgrade your pen capacity so you can place more hybrids at once.
- Upgrade the treadmill so leveling takes less time.
- Shiny hybrids are rarer than standard ones.
Eggs and what comes out of them
TableEggs are items you collect and hatch to receive new animals or hybrids. There are three egg types: Common, Epic, and Chaos. An egg takes up one pen slot even before it hatches.
| Common egg | hatches into a new animal, widening your fusion options. |
| Epic egg | higher chance of producing an unusual hybrid. |
| Chaos egg | the rarest type, with the best chance of a special hybrid outcome. |
| Standard hybrid | the normal result of fusing two different animals. |
| Shiny hybrid | a rarer fusion result with a glowing appearance, harder to obtain than a standard hybrid. |
Upgrade priority
SummarySpend the money your hybrids earn on upgrades to keep the whole loop accelerating. Both the pen and the treadmill have upgrades worth buying.
- Pen capacity lets you place more hybrids at once, directly increasing total $/s.
- Treadmill speed cuts the time it takes to level up a hybrid before it goes into the pen.
