One of the most retold moments in Star Wars history is Boba Fett's escape from the Sarlacc Pit, which has led to confusing timelines in the past. If all stories about Boba Fett's escape are considered part of the Legends canon, Boba Fett fell into and then escaped the Sarlacc Pit a total of three times, which is impressive. In the current Star Wars canon, Boba Fett only fell into and escaped the Sarlacc Pit once, as revealed through flashbacks in The Book of Boba Fett.
