The well-known Mario jumps out of a random bright-green pipe, doing a backflip as he makes a perfect landing, even doing a couple of backflips forward for a few seconds before standing up, he adjusts his hat and looks around, wondering where he happened to be now.

"Huh, Wonder where I am-a. ..Doesn't matter, let's-a go!"
