The Toon Rainbow is an Uncommon Boost in Fortnite, carrying over the bright multicolor trail that Rocket League players know from the game’s Rainbow Rocket Boost. It debuted during Chapter 7, Season 3 and slots into your car cosmetics for Rocket Racing, adding a sparkly rainbow stream behind your vehicle.
Quick answer: Toon Rainbow is a free Boost tied to the Rocket League crossover. Once it is granted to your account, it appears in your Locker under Boosts and can be equipped immediately. No official free-claim date is currently confirmed.
Toon Rainbow Boost details
The item is a cosmetic Boost, which is the trail effect applied to your car in Rocket Racing. It is not a gameplay upgrade and does not change speed or handling. Its rarity sits at Uncommon, and it shares its rainbow look with Rocket League’s Special-quality Rainbow Rocket Boost.

How the free Toon Rainbow Boost is granted
Toon Rainbow is distributed as a free reward connected to the Rocket League crossover rather than as an Item Shop purchase. Free cosmetics like this are added directly to your account, so there is no code to redeem and no currency to spend.
Note: If a specific claim window or task is required, it will be announced through Fortnite’s official channels. No official next date or claim requirement is confirmed at this time, so avoid third‑party sites that ask for logins or payment to “unlock” the boost.
How to confirm you own it
You know the grant worked when Toon Rainbow shows up in your Locker under Boosts. Select it, equip it to your car, and start a Rocket Racing match to see the rainbow trail in action. If it is not there yet, close and relaunch Fortnite so the account can sync your latest rewards.
Because Toon Rainbow is a cosmetic Boost, it stays in your account permanently once granted. There is nothing else to buy, and the effect carries across every Rocket Racing session as long as it is equipped.
