Both franchises already have a presence on Roblox--SpongeBob is included as part of Nickelodeon's Nickverse game, while TMNT has a game called Turtle Trouble that launched in 2007.

The "SpongeBob SquarePants" and "Teenage Mutant Ninja Turtles" Roblox experiences will be separate entities and are still being developed. Both immersive experiences will launch later in 2023.
