Mario, Luigi, Daisy, Peach, Rosalina, Wario, Waluigi, Pauline, Toad, Birdo, Yoshi, Kammy, Dry Bowser, Toadette, Bowser, Diddy Kong, Donkey Kong, Dixie Kong, Koopa Troopa, and Dry Bones are all at the Mansion.
Mario, Luigi, Daisy, Peach, and Rosalina are talking together. Wario and Waluigi are playing pranks on the monkeys(which is a dumb idea). Pauline, Birdo, and Yoshi are talking about their costumes.
Bowser, Kammy, and Dry Bowser are... well... being evil as always and talking about castle plans. Toad and Toadette are skipping around for some reason. Koopa Troopa and Dry Bones are bickering about who knows what.
