Peach was about to be kidnapped by Bowser (again). She was all alone because Mario was gone and no one else was in the castle. While Bowser went on about how things would be easier if she just married him, Peach then struck a deal by inviting him to her bed for tonight in exchange for not kidnapping her, and if she ended up pregnant with his baby, she'd marry him.

A Fear of Shots
Dr. Mario tells Dr. Crygor that Penny needs a shot, but she's too scared of shots. When Crygor angrily yells at Penny and scolds her for being scared of shots, she becomes heartbroken and cries. Was Dr. Crygor too harsh? (I did this since Penny is listed as a Mario character, I figured I'd be the one to have the first Mario story with her listed.)
