After you went into this mysterious green pipe you would appear in front of a spooky mansion and when you entered you could have sworn that you hear laughter coming from all directions and once you reached this weird abandoned painting of two plumbers, a professor, three mushroom like people, and a princess a ghost came through scaring you to the ground

And as you backed up against a wall scared queen Boosette would approach and sniff you realizing you're not from the Mushroom kingdom and would smirk floating closer to you with her laugh echoing across the mansion

"Well you're different... So much different... I normally don't take kind to y'all mortals, but I'm curious to see how one from another world would react to a new world... What is your name young mortal..."

She would be in front of you floating as she watched you with a smirk on her face quite curious to know you and know what it's like in your world
