Sell Ores Pet Auto-Hatch Script

The pet auto-hatch script is the most complex automation in Sell Ores. It watches your pet slots, hatches new pets when an egg is available, applies Growth Gems to the highest-priority pet in your roster, and triggers fusion when you have enough duplicates. Combined with the Best Pets tier list it lets you push the meta pet chain overnight without manual clicking.

What pet auto-hatch actually does

The script runs five background tasks:

1. Auto-hatch — spends Cash on the cheapest available egg every 60 seconds.
2. Pet inventory watcher — keeps a count of every pet tier you own.
3. Fusion walker — fuses duplicates when you have enough to advance one tier.
4. Growth Gem router — applies the next queued Growth Gem to your highest-priority pet.
5. Pet log overlay — optional HUD that shows the current fusion chain progress.

You can toggle each task independently. Most players run tasks 1, 3 and 4 and disable task 5 to keep the screen clean.

Executor setup

The script runs on any of the popular executors. The same setup as Auto-Sell applies — install, launch Sell Ores, paste, execute. The script is longer than the other automation scripts, so allow a couple of seconds for the executor to inject.

The most reliable executor choice for the pet auto-hatch script in August 2026 is Wave for free users and Synapse X for paid users. Velocity has a known issue with the Growth Gem routing subsystem on Floor 7.

Best pet targeting

Out of the box, the script uses this priority list to decide which pet to spend Growth Gems on:

1. Devil’s Snacc (S tier)
2. Cosmic Ram (S tier)
3. Infernal Cat (S tier)
4. Lava Wolf (A tier)
5. Magma Cub (A tier)
6. Crystal Fox (A tier)
7. Phoenix Chick (A tier, Floor 4+ only)

You can edit the priority list inside the script’s settings block. The settings block is the JSON object at the top of the script. The default is fine for 95% of accounts — but if you are pushing for a specific pet (say, Infernal Cat for the Magmaite Ore combo), set that pet to priority 1.

Fusion chain walker

The fusion walker respects the official fusion recipes. It will not fuse a Common pet into an Epic pet directly — only duplicates of the same tier can be fused. The walker advances one pet per fusion cycle, so a 4-step chain (Common → Uncommon → Rare → Epic → S-tier) takes 4 separate fusion cycles.

Fusion cooldown is 12 hours per pet slot. With 4 pet slots you can fuse once every 3 hours on average, which means a full chain advance every 12 hours. Plan your Cash flow around that.

Growth Gem routing

Growth Gems come in three sizes:

• Small Growth Gem — +1 fusion tier (1 step).
• Medium Growth Gem — +2 fusion tiers (2 steps).
• Devil’s Growth Gem — +3 fusion tiers (3 steps), the strongest.

The script applies the next queued Gem to the highest-priority pet that can still benefit from it. The PETFUSION code gives a Devil’s Growth Gem — the script will route it to your Devil’s Snacc chain by default.

Safety checklist

• Pet slots are limited — the game gives you 4 pet slots on a fresh account. The script does not free up slots automatically.
• Fusion is irreversible — once two pets are fused, they are gone. The script will not undo a fusion even if you misclick.
• Run on a fresh alt first — if the Growth Gem router has a bug, you can lose a Devil’s Gem that took weeks to acquire.

Troubleshooting

• Script does not hatch — check your Cash. The auto-hatch task waits until you have at least 10x the cheapest egg cost.
• Growth Gem not applying — open your inventory and check the pet is in a slot. The script cannot apply a Gem to a pet that is in the Egg screen.
• Fusion walker stalling — confirm you have the right duplicates. The walker cannot fuse across tiers.
• Pet log overlay glitching — toggle task 5 off with F10.
