Ride A Pet Rebirth 1 is the progression requirement for unlocking the limited Fuse Machine. You need $1 million Cash and one Horse before the first rebirth can be completed, and the machine near spawn remains hidden until that step is finished.
The Horse is the part most likely to slow players down. It is a Legendary pet from the Glass Egg, so having enough Cash does not automatically make Ride A Pet Rebirth 1 available. Keep the Horse ready for the requirement, then use the Rebirth button on the left side of the screen.
Ride A Pet Rebirth 1: requirements
The first rebirth checks for $1 million Cash and one Horse. When both are ready, open the Rebirth menu, review the requirements and confirm the progression step.
Do not sell the Horse while preparing Ride A Pet Rebirth 1. The game checks the pet as well as the money total, which is why a player can reach the Cash target and still be unable to finish the rebirth.

How to get the Horse
The Horse needed for Ride A Pet Rebirth 1 is a Legendary pet from the Glass Egg. Current live guides report a 1 in 500,000 hatch chance, making the pet a bigger bottleneck than the money requirement for players who already have a strong earning setup.
A Royal Radar can help locate the Glass Egg more efficiently, but it does not guarantee the Horse. Keep hunting the correct egg type rather than switching to a different pool and expecting the rebirth requirement to complete anyway.
How much Cash do you need?
Ride A Pet Rebirth 1 requires $1 million Cash. Treat that as a hard threshold and then separately verify the Horse, because neither requirement substitutes for the other.
The current Fuse Machine event advertises 2x Cash, making the event window a useful time to push the money requirement if you are close. Use the live event indicators to see where the boost is applying rather than assuming every system is doubled.
How to complete Rebirth 1
Once the Cash and Horse are ready, press the Rebirth button on the left side of the interface and confirm the first rebirth. Let the game apply the progression change, then return to the spawn area.
After Ride A Pet Rebirth 1 is complete, look left of the Phoenix near Ride Pet with Friends. The Fuse Machine should now be visible, which is the main reason many players are rushing the first rebirth during this limited event.
Why Rebirth 1 matters now
Without Ride A Pet Rebirth 1, the Fuse Machine does not appear and you cannot access its 16 reported exclusive fused pets. That makes the first rebirth an event gate rather than simply another long-term progression milestone.
If your goal is collecting the limited fused pets, prioritise the Horse and Cash before unrelated progression. Once the rebirth is done, later fusion attempts become a matter of collecting four qualifying pets and paying the displayed cost.
What can you do after Rebirth 1?
The immediate event benefit from Ride A Pet Rebirth 1 is access to the Fuse Machine. Load four Legendary-or-higher pets, inspect the possible results and decide whether the Cash cost, timer, Mutations and Traits are worth the attempt.
The timer continues while you are offline, so unlocking the machine early gives you more time to cycle attempts. Start a fusion, leave if needed and come back when the countdown should be finished.
Rebirth complete but machine missing
If Ride A Pet Rebirth 1 is definitely complete and the machine is not beside the Phoenix, rejoin a fresh server first. That refresh is simple and avoids wasting time on fixes when the account may just be sitting in an older server state.
If the machine still fails to appear on a confirmed rebirthed account, the issue is outside the normal unlock rules. At that point a live bug report is more appropriate than farming another Horse or more Cash.
