Despicable Me Minion Mayhem is a motion base show in Production Central at Universal Studios Florida. While it's not a "must do," it is also recommended. The minimum height to ride is 40 inches.
Minion Mayhem replaced the Jimmy Neutron attraction at Universal Studios Florida in July 2012. You'll enter Gru's house, then walk into his secret laboratory, where you'll be transformed into Minions to do Gru's work. Of course, it all goes wrong, as you ride in moving seats for this 3D film. After the show, you can meet and dance with Universal's popular Minions in a post-show "dance party," before exiting through the Minion-laden gift shop.
