Mattel, Inc. and Roblox Corporation today announced an expanded collaboration to introduce a series of new Roblox titles inspired by some of Mattel’s most celebrated brands.

Monster High, Mattel’s premier self-published Roblox experience, debuts October 24. Fans can step inside the haunted halls of Monster High like never before—customizing their pet “Creepanions,” crafting powerful elixirs in Frankie Stein’s Alchemy Lab, and joining Clawdeen Wolf’s pack to fuel the legendary Ghoulstone for fang-tastic rewards. Featuring iconic characters, endless style options, and secrets lurking beneath the school, the experience invites players to team up, show their claws, and discover that monster magic never goes out of style.

Building on the global success of Monster High, the No. 4 doll brand worldwide*, the franchise now translates its signature play patterns into Roblox's interactive digital world. Additional experiences will follow, bringing beloved franchises like Barbie, Hot Wheels, Masters of the Universe, UNO, and more to life through a dynamic lineup of standalone Mattel games on Roblox.

Additionally, as first announced at the 2025 Roblox Developers’ Conference (RDC), Polly Pocket and Street Sharks are now available on the Roblox License Manager and Licenses catalog, with Matchbox and Rock ‘Em Sock ‘Em Robots coming soon. This program enables IP holders to bring their properties into immersive digital play at scale, giving Roblox developers access to officially licensed assets for gameplay and fan creations.

Ron Friedman, Vice President, Mattel Future Lab, said: “Roblox is one of today’s most imaginative platforms, and this collaboration opens new ways for fans to experience Mattel’s brands. We’re starting with Monster High, with more standalone experiences and engagement through the License Manager to follow. Together, we’re creating worlds that seamlessly bridge physical and digital play.”
