Regular Fool's Paradise

Rigby gets to hang out with the gloomiest of the Loud Siblings, doing everything in his power to force her out of her comfort zone and unleash her fun and optimistic side by having her play video games, eating, and tuning in some music. But Lucy tells him a very humiliating secret; every April Fools, Luan would somehow become psychotic and she would prank her family in the most dangerous and potentially fatal ways, and that one time that her body turned yellowish white was due to being poured bleach on her. Rigby, being the impulsive loose cannon that he is, vows to pay Luan back a new butthole for using a dangerous substance on her siblings. Since Lucy likes Halloween stuff, Rigby invites the best friend of legendary prankster Mitch "Muscle Man" Sorrenstein, Hi-Five Ghost, for advice on pranks. Remembering the Prank War between Gene and Rigby's boss Benson, and his experience with the Master Prank Caller, Rigby decides to return home to pick up a familiar item of that experience.

Sequel to Loud Prank Callers and the Regular sequel to "Fool's Paradise".
