Families that visit select Walmart stores this summer are in for a fun Nintendo surprise. Nintendo is teaming up with GameTruck and Walmart to create a “Summer of Fun” in parking lots at 100 Walmart locations around the country.

Launching on June 23 and running until Aug. 19, the Nintendo Switch Summer of Fun will feature demos for Nintendo Switch games like Super Mario Odyssey, Mario Tennis Aces, Donkey Kong Country: Tropical Freeze and Mario Kart 8 Deluxe. Visitors will also be able to take part in family photo sessions and meet costumed characters like Mario (at select locations). The game demos and Nintendo activities are open to everyone, and there is no cost to attend.

“We love bringing families together through our systems, games and lovable characters,” said Doug Bowser, Nintendo of America’s Senior Vice President of Sales and Marketing. “Delivering hands-on demos and unique Nintendo experiences directly to families at Walmart showcases the social fun and portability of Nintendo Switch.”

For a great photo-worthy moment, attendees will have the chance to take a memorable family picture together and select a custom backdrop inspired by the various kingdoms in the Super Mario Odyssey game. At select locations, families might even be able to meet and snap a picture with Mario himself!

While enjoying the Nintendo fun, attendees will have the opportunity to enroll in the My Nintendo Summer of Fun sweepstakes for a chance to win round-trip tickets for a family of four to visit any location that Southwest Airlines flies to. By winning this sweepstakes, families inspired by the colorful and exotic kingdoms in the Super Mario Odyssey game will be able to fly to a similar real-life location, like New York (Metro Kingdom), Denver (Snow Kingdom) or the Caribbean (Seaside Kingdom).

In addition to the grand prize winner, 100 runner-up winners will each receive a Nintendo Switch prize pack, which includes a Nintendo Switch system, Nintendo Labo Variety Kit, and the Mario Kart 8 Deluxe, Super Mario Odyssey and Mario Tennis Aces games. Anyone that can’t make the Summer of Fun event can enter the sweepstakes online by visiting here.
