Cinnamon Toast Crunch Cinnamojis are teaming up with WWE for limited-edition boxes featuring Rey Mysterio and a surprise Cinnamojis takeover during their first-ever WrestleMania appearance.

Fans can exclusively find the limited-edition Cinnamoji Toast Crunch, Rey Mysterio WrestleMania 39 cereal box in limited quantities on Walmart.com starting this month, while supplies last. To add to the fun, they can use the back of the cereal box to build their own popup wresting ring.

“Cinnamojis are always up for anything and given the chance to adventure into a world of wrestling with spirited characters, colorful masks, and enthusiastic fans, they were all in,” said Mindy Murray, Sr. Marketing Communications Manager for General Mills. “WWE is at the epicenter of sports entertainment, and we are thrilled to bring Cinnamojis’ antics to their passionate fanbase.”

To celebrate the Cinnamoji Toast Crunch cereal, Cinnamon Toast Crunch and WWE are teaming up to bring Cinnamojis to fans live during WrestleMania 39, hosted at SoFi Stadium in Los Angeles April 1-2.

“Cinnamon Toast Crunch is an enduring brand with an amazing product, and we’re excited to welcome them as a first-time WrestleMania sponsor,” said Craig Stimmel, Head of Global Sales and Partnerships, WWE.
