The Firework glove in Slap Battles lets you launch fireworks with its special ability, and unlocking it is tied to the Easy As Pie badge. The catch is that you cannot buy it with slaps or Robux. You have to bake and eat a Birthday Cake using two other gloves working together.
Quick answer: Equip the Alchemist glove, find the Cake Mix on the ground in the Normal Arena, have a friend with the Oven glove slap you to turn it into a Birthday Cake, then eat the cake from your inventory. This awards the Easy As Pie badge and the Firework glove.
What you need before you start
Two gloves must be present on the same server, and they cannot both sit on one player at once. Line these up first, or the Cake Mix cannot be turned into a cake.
| Requirement | How it is obtained |
|---|---|
| Alchemist glove (yours) | Reward for the Containment Breach badge |
| Oven glove (a friend) | Purchased with 33,000 slaps |
| Cake Mix | Found on the ground in the Normal Arena using Alchemist |
A private server makes this far easier, since you control who is present and can coordinate the Oven slap without interruptions.
Unlock the Alchemist glove first (Containment Breach badge)
The Alchemist is the tool that lets you locate the Cake Mix, so it has to come first. It unlocks with the Containment Breach badge, which asks you to eliminate 10 opponents using the special ability of either the Plague glove or the Zombie glove, all without dying yourself.
Both of those abilities have a cooldown between uses, so a public-server run can stretch out for a long time, and one death resets your progress. Bringing one or two friends into a private server and repeatedly slapping them with Plague or Zombie is dramatically faster and removes the risk of being knocked off yourself.
Note: You keep the Alchemist permanently once the badge pops, so this step only needs to be done once.
Bake and eat the Birthday Cake to get the Firework glove
With the Alchemist equipped and a friend holding the Oven glove, work through the sequence below in the Normal Arena.
How to confirm it worked
Eating the cake pops the Easy As Pie badge on screen, and the Firework glove is added to your collection right after. If both appear, the unlock is complete and the glove is yours to equip.
Common reasons it does not trigger
- The Cake Mix has not spawned yet. Reset the Normal Arena and keep searching with Alchemist.
- No one in the server has the Oven glove, so the mix cannot be baked into a Birthday Cake.
- You never ate the cake. Picking it up is not enough; you must eat it from the inventory to receive the badge and glove.
Because the whole chain depends on the Alchemist, the Oven, and a lucky Cake Mix spawn, the fastest route is almost always a private server with a cooperating friend. Get the Containment Breach badge out of the way, bring an Oven user along, and the Firework glove is only a few slaps and one slice of cake away.
