The Fuse Lab is on the left side of Bike For Egg's Safe Zone, near the Sell Shop. It turns three similar pets into one egg, but all three pets are permanently deleted when you fuse.
Where Is the Fuse Lab in Bike For Egg?
You can use the lab during the in-game day or night, so there's no particular cycle to wait for.

How to Use the Fuse Lab in Bike For Egg

- Interact with the Fuse Lab to open its menu.
- Select three similar pets of the same species. Pets of any rarity or weight can go in, and the egg you claim will be that species. The menu protects favorited pets and pets on your base, so favorite any pet you want to protect or keep it on your base before selecting.
- Read the Money charge at the bottom of the menu. The three-Chicken example costs 1,000 Money; use the amount shown for your fusion rather than treating that example as a flat fee.
- Check your three picks, then press Fuse. The lab permanently removes all three pets.
- Wait 60 seconds, then claim the egg.
Egg Size and Mutations After a Fuse
Fuse Lab eggs are usually large, but a smaller result is possible. A smaller egg hatches a mini pet with lower earnings, so don't count on fusion as a guaranteed size upgrade.
The best mutation among your three pets carries over to the egg. If you care about a specific mutation, make sure it comes from one of your three picks.
