Adam's rampage throughout the town while he was enlarged may not have been as harmless as the film makes it look. After escaping from his house, Adam goes to a house where a birthday party is being held in the garden and shows Big Bunny to the young guests during a magic show performed by a female magician, leading to the magician fainting into the garden's pool. As all of the guests run away due to being scared, no one is shown retrieving the unconscious woman. So, yeah, even if he just meant to have fun, Adam may have committed manslaughter.
