S04E31 Bound in Chains; Get the Gator; Heli Rope Transfer
In this special episode featuring female models, the first challenge involved the contestants being bound in a weighted vest and submerged underwater. They had to release three sets of clasps to escape and swim to the surface, with the four fastest ladies moving on while the other two were eliminated. Next, the competitors faced a swamp obstacle course to locate three keys, each hidden at different challenges. They navigated over six buoys, leaped over a boat, climbed a tree, and plunged back into the water. Once onshore, they had to determine which key opened a tunnel. Inside, they had to drag out an 8-foot, 400-pound alligator by its tail. The three quickest would progress to the final round, while the rest would be sent home. The last stunt was the Heli Rope Transfer.
