Despicable Me Minion Mayhem is a motion base show in Upper Lot at Universal Studios Hollywood. It's worth seeing on a time-permitting basis. The minimum height to ride is 40 inches.
Walk through the door to Gru's house, then enter his secret lab, where you'll be turned into a minion and put through training by Gru's daughters. Of course, everything goes horribly wrong along the way, but it's the minions, so everyone has a fun time. This is a 3D movie, motion simulator ride.
