The Nintendo World Store in Rockefeller Center shone bright with neon Mario colors, a welcoming warm oasis on a wet, cold November morning.

Whether dressed in a Princess Peach costume or in an edgy, unauthorized fan art shirt, gamers came decked out in their finest Mario gear for the occasion.

Customers entered the Mario museum in the same way the mustached plumber first discovered the Mushroom Kingdom long ago -- by entering a giant green pipe.

The pipe theme continued inside the museum, with unique items from Mario's merchandising career laid out on pipes and inside secret blocks.

Try to guess what this is. Lunchbox? Pencil case? No, it's a vintage Super Mario cassette tape caddy. Remember those?

Take a Mario bubble bath, wash your hair with Princess Peach shampoo, then remove any unwanted body hair with Luigi Depilatory Cream (not pictured).

Get dressed in your finest Mario vest and make your own cartoons with a rubber stamp set.

On this Thermos lunchbox combo, the Marios hit the couch and play The Legend of Zelda. How recursive.

Before hitting it big with home games, Nintendo was well-known for its Game & Watch handheld amusements. This Mario game let one player control both of the Bros.

The Super Mario Bros. 3 Walkie Talkie set lets you bark orders right into Mario's horrific contorted grimace.

Speaking of horrific grimaces, if I saw the face on this Mario comforter staring up at me when I woke up in the middle of the night, I'd be somewhat less than comforted.

The Super Mario Bros. Super Show was required after-school viewing for a generation of kids. These VHS tapes capture the action for all eternity, or at least until the tapes fall apart.

Super Mario Bros. cake pan. This probably sounds like a great idea except when you realize that the finished product isn't going to look like much of anything unless your mom is an expert at drawing with cake icing.

A wicked Mario Halloween costume, vintage Dr. Mario poncho and a Super Mario Bros. 2 racing outfit complete this wall of disguises. Wait, what? There was no racing in Super Mario 2.

No museum would be complete without the games themselves, including Super Mario 1, 2, and 3 for the 8-bit Nintendo.

Mario's next two grand adventures, Super Mario World and Super Mario 64.

A television monitor in one corner of the museum ran a loop of classic Super Mario TV commercials that fans probably hadn't seen since the '80s.

Fans could finish out their Mario-themed day by getting their pictures taken with Mario-themed props and backgrounds.

And what Mario day would be complete without some face time from the man himself?
