March 10 was chosen by fans of the game as the date for this holiday because March 10 when abbreviated and written without a space between the month and date – Mar10 – looks like the word Mario.

Fictional Italian Plumber

The Super Mario video games follows the adventures of Italian plumber Mario and his brother Luigi while they try to rescue Princess Peach from the evil Bowser. Princess Peach is the princess of the fictional Mushroom Kingdom in which the game is set.

Best-Selling Game

Considered to be the best-selling video game of all time and one of the most recognizable video game characters in the world, Mario was created by Shigeru Miyamoto. Since his first appearance in the 1981 Nintendo game, Donkey Kong as Jumpman, Mario has featured in over 200 video games, and several television shows and comics.

How to Celebrate?

  • Spend the day playing the iconic game.
  • Have a super Mario themed party. Serve star shaped cookies , mushroom shaped cupcakes, and chocolate coins.
  • And if you are brave enough, why not dress up like Mario for the day?

Did You Know…
