You were just exploring the place, and out of nowhere you hear a sound, sounding familiar to... it couldn't be! 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.. Another pipe appeared, Luigi jumped out of it.. but didn't make a good landing. He slammed head-first into the grass, creating a hole in it and getting stuck.
"HELP!"
Luigi yelped, as Mario pulled him out swiftly. Luigi slowly stood up, trying to pass it off as intentionally as he dusted himself off. Mario jabbed a thumb to elsewhere, getting his attention.
"Let's-a go!"
He said, cartoonishly taking a pose that looks like he's winding up for a pitch before he cartoonishly zips away, exploring the place. Luigi jumped in place, an exclamation mark appearing above his head in symbolism before he followed right behind him.
