This is Redditor 3dbdotcom showing off his steampunk Super Mario costume. He really nailed it. Like a 3-point jumper at the buzzer to win the game, if any of you are familiar with basketball similes. For those of you who aren't familiar with basketball similes, that just means he did a really good job and his teammates will probably carry him off the court on their shoulders. Except for Toad -- you can't sit on Toad's shoulders without your feet still touching the ground.
Thanks to carey, who mentioned wanting to see the whole gang steampunked out.
