Nintendo’s first major full game release on mobile, Super Mario Run, launches next week on December 15. To promote its upcoming release, Nintendo of America’s effervescent president Reggie Fils-Aimé appeared on The Tonight Show with Jimmy Fallon.

A new live-action trailer for Super Mario Run was revealed, and Fils-Aimé helped guide Fallon through a level. While the game won’t be available until next week, they announced it will be playable at some Apple stores starting today.

Fils-Aimé then surprised everyone when he also brought out a Nintendo Switch, Nintendo’s upcoming console. They didn’t waste any time and jumped right into Nintendo’s most anticipated game: The Legend of Zelda: The Breath of the Wild. This was a rare moment when we see the title running on Nintendo Switch instead of the Wii U version.

Fallon brought his usual child-like glee and excitement over the new console. He was particularly impressed by the way the Joy-Con splits into multiple forms or even separate controllers for two players.

As an extra treat, legendary game designer and Nintendo godfather Shigeru Miyamoto was in the audience. Later he joined The Tonight Show’s band the Roots for a rendition of the classic Super Mario Bros. theme.

While gaming becomes more mainstream with each passing year, it’s still nice to see it displayed on late night television. While Conan playfully mocks games to crack some jokes, Fallon frequently celebrates gaming and game designers on his show.

Super Mario Run launches December 15. It’s technically free-to-play, but the free version is basically a limited demo. The full game can be unlocked for $10. The Nintendo Switch is due out in March 2017.
