Mario Day

Mario Day (also written as Mar10 Day ) is an annual celebration of the entire Mario franchise. It takes place on March 10th each year because the date, written as "Mar10", looks like "Mario". The holiday could be celebrated by dressing up as Mario, having a Mario-themed party, or simply playing Mario games, among others. Although the holiday was not created nor declared by Nintendo, the day was unofficially celebrated by most Mario fans. Since 2016, Nintendo has officially embraced the holiday and started celebrating annually by promoting Mario games and holding Mario-themed events. On an newscast on March 10, 2017, the headline "National Mario Day" was played celebrating Mario Day where the reporter talked about Mario Day, its name and Mario.

The video is about a person in a Mario costume walking around Nintendo's office turning things into Mario-related objects such as turning notepads into Nintendo 3DS systems. The person also adds Mario-related objects to the office such as several Mario plushies to a person's desk.
