Place eggs and hatch animals

The steal is the exciting part. Hatching is what the official description pays you for. Animals earn money, including offline. An egg that never hatches is not an earner.

Individual animal names and cash rates are not published as a stable list. Thumbnails that shout a trillion per second are ads. Compare the income tooltip on your pen after every hatch, especially after the 2 October 2026 update stamp.

Place and hatch

1. Return to the plot with the egg.
2. Use a free pen slot.
3. Confirm the egg is actually seated.
4. Finish the hatch until an animal is there.
5. Read its income tooltip. If the UI has a separate equip action that the tooltip says raises cash, equip the stronger animals. If only pen occupants pay, filling slots is the whole job.
6. Decide the next steal, or a sale, from that number.

If placement fails, you are at capacity. Buy pen space or sell the weakest earner before the next lava run. Spend order: upgrades.

Slot rules

• Full pen and a clearly better egg: sell the lowest earner or buy a slot, then hatch.
• Full pen and a mid egg: skip that steal and train instead.
• Empty slots while you are about to log off: you are giving up offline cash. Hatch first.

Early on, any animal beats an empty pen, so Grass hatches are correct. From Beach and Underwater upward, one stronger hatch can beat several old fillers. If the new animal does not beat your weakest slot, do not force it in.

What to sell

Sell when the new hatch earns more and you need the slot. Keep a collection animal only after the income slots are already healthy. Do not sell your only mid-biome earner for a cosmetic look.

Re-check tooltips after a patch. The egg tier list ranks biomes by how hard they are to steal versus how far they move your pen, not by a fake dollars-per-second table.

A session that actually hatches

1. Claim offline cash when you rejoin.
2. Hatch anything waiting.
3. Sell an obvious dud if a better egg is in hand.
4. Train briefly.
5. Steal one targeted egg.
6. Hatch again.
7. Buy capacity or a useful trail only if a real bottleneck showed up.
8. Leave with the pen full. Details: offline earnings.
