Bike For Egg Fuse Lab Guide – Turn 3 Pets Into 1 Egg

What are the Fuse Lab rules?

The Fuse Lab accepts three pets of the same species and returns one egg of that species. It costs Money, takes 60 seconds, and destroys the inputs. There is no way to cancel a fusion or recover the pets once you press the button.

The menu shows the exact Money cost after you select the three pets. The price scales with the pets involved, so a Chicken fusion is cheap while rarer species cost more.

Where is the Fuse Lab?

The Fuse Lab is in the Safe Zone, on the left side, beside the Sell Shop. It is open at any point in the day-night cycle, so you do not need to wait for a specific time.

Both shops sit close together, which makes the sell-or-fuse decision easy: you can compare the Sell Shop offer with the Fuse Lab cost in one trip.

How do you fuse pets step by step?

1. Walk to the Fuse Lab in the Safe Zone and interact with it.
2. Select three pets of the same species from the menu.
3. Check the Money cost at the bottom of the screen.
4. Press Fuse. The three pets leave your collection and the 60-second timer starts.
5. Return when the timer ends and claim the egg.
6. Hatch the egg to see the new pet’s size.

You know the fusion worked when the inputs disappear from your collection and a claimable egg appears at the Lab. If your balance is too low, the Fuse button will not complete the action, so top up first.

What size is the resulting pet?

The result is usually a large egg, which hatches a heavier pet than the three inputs. That is the main reason to use the Lab: size affects income, so three small duplicates can become one better earner.

It is not guaranteed. Sometimes the Lab returns a small egg, which hatches a mini pet with a low earning rate. Because the inputs are already gone at that point, treat every fusion as a gamble rather than a guaranteed upgrade.

How do mutations work in the Fuse Lab?

Mutations can be fused. If any of the three pets you submit carries a mutation, the best mutation among them transfers to the resulting egg.

That creates a clear rule: never sell a mutated duplicate if you can fuse it. A mutated pet used as one of the three inputs can pass its bonus to the result, while selling it gives only a small amount of cash.

The pet rarity guide explains how rarity, size and mutations affect income. For the other half of the progression loop, see the bike list and the Trails list.

Should you fuse or sell duplicates?

Fuse, unless you cannot afford the Money cost or the species is one you want to keep as separate pets.

Selling is instant and risk-free, but the payout is low. Fusion takes a minute and can fail to produce a large pet, yet the expected result is better for your base.

What is the cheapest way to try the Lab?

Collect several eggs in the Jungle biome, hatch three Chickens, and fuse them. The Chicken fusion costs 1,000 Money, which is low enough to test the full process — selecting pets, paying, waiting and claiming — before you risk anything rarer.

Once you understand the timing, move on to fusing your mid-tier duplicates. Keep your best pets out of the Lab entirely.
