How did Boba Fett survive the sarlacc?
After conversing with a fellow captive, Susejo, Fett discovered that this being was actually psychologically connected to the Sarlacc. Fett used this to goad the creature into contracting around his jet pack, igniting the device and providing his means of escape. After escaping the sarlacc, Fett used his wrist flamethrower to scorch and kill the sarlacc. The resulting explosion, combined with the beast’s acidic stomach juices, left Fett on the verge of death. As he lay dying on the surface of Tatooine, his colleague Dengar was searching for anything valuable left from the explosion, but found Boba Fett instead, and nursed him back to health.
