Goosebumps 2: Haunted Halloween follows the Quinn family – high school senior SARAH (Madison Iseman), her middle school brother SONNY (Jeremy Ray Taylor), and their mother KATHY (Wendi McLendon-Covey) -- into an entirely new set of spooky, exciting, and funny events. Sonny and schoolmate SAM (Caleel Harris) are best friends with a side job as the “Junk Brothers,” collecting discarded stuff other people don’t want. But it’s a gig that unfortunately leads them right into the path of (gulp) SLAPPY (Avery Lee Jones), the mischievous ventriloquist dummy from an unpublished Goosebumps book.
