When an alarm goes off in Josh’s underwater lair, Finn and Jake discover an old timey recording with . . . instructions. Too bad they don’t have the patience to listen all the way through—otherwise they would have heard the part about . . . their new sister?! It’s memories versus curses as our two best pals do what they do best: break statues and cause a ruckus. Christopher Hastings (Gwenpool) and Zachary Sterling (Adventure Time: Seeing Red) return to this Eisner Award-winning series with all-new adventures starring holo-dads and more.
