Denny’s is roaring cross-country with a custom-wrapped Masters of the Universe Mobile Diner, created in partnership with Mattel, Inc. and Amazon MGM Studios. The activation kicked off in Spartanburg, South Carolina, as the truck loaded up and hit the road to Los Angeles for fan-fueled events leading up to the movie’s June 5 premiere.
The 53-foot tractor trailer is wrapped to resemble a giant, roaring Battle Cat—the loyal, armored green tiger steed of He-Man. It features a fully functional commercial kitchen, including ovens, grills, a walk-in cooler, and a commercial coffee maker, capable of serving thousands at each stop.
“At Denny’s, we believe every meal should feel like a victory. By bringing the world of Eternia to life through our Mobile Diner, we’re giving fans a chance to experience the power of Grayskull beyond our restaurant booths,” said Chris Bode, President & CEO, Denny’s. “This journey is our way of celebrating the fans whose passion has kept this legend alive, rewarding their loyalty with epic prizes as we charge toward the Masters of the Universe premiere.”
Fans can experience the truck at Fiesta Broadway on April 26 in Los Angeles, one of the largest Cinco de Mayo celebrations in the country. Denny’s will offer free tastings of new Masters of the Universe menu items, photo opportunities, and movie swag.
