Magic tonics? Soos winning at something? Dipper and Mabel’s summer vacation gets even weirder as they encounter increasingly mysterious phenomena in Gravity Falls: Mabel runs the Mystery Shack with (almost) disastrous consequences; the Gravity Falls crew falls into a bottomless pit; and the twins make an unusual new friend when the local pool opens on the hottest day of summer. Volume 5 of Gravity Falls Graphic Adventures retells episodes 13–15 of season 1: Boss Mabel, Bottomless Pit! and The Deep End.
