Soon after entering the prison, Serious Sam finds the Shaman and rescues him. The Shaman decides to take a shortcut, leaving Sam to fight through the prison and rescue any Simba prisoners still trapped in the prison. Along the way, he finds a strange, sparkly thing that teleports in a large amount of enemies. Eventually, he reaches a large area with a pool at its bottom. He climbs to the top of the area, then clears out one last part of the prison before entering the Shaman at the Ursul Gardens.
