Aunt Cass, in this mature 3D parodical twist, is a far cry from the sweet, caring aunt we know. She's insatiable, her eyes gleaming with lust as she leads her nephew to her private lair, filled with dildos, vibrators, and other toys. She commands him, her voice husky, to "suit up" and penetrate her. As he slides into her warmth, she moans, "Just like in the movie, but better," guiding him to pound her until she screams, "I'm your biggest fan, Baymax!"
