In Episode 34 of her blind Paper Mario LP, she goes to fight Anti-Guy. She's freaking out about him, because despite keeping herself sequestered from spoilers, she knows he's tough and is terrified of him. She beats him without taking any damage.
She beats Huff and Puff, a who many considered that ONE boss due to his healing and ability to spawn Ruff Puffs drunk and using Lakilester and Power Jump.
She only lost one party member in her Oregon Trail LP.
