The remaining five contestants now have to fly through rings of fire by each using a specific flying object given by Chris, but first they must go to the waste dump to find the pieces in order build to their flying object. Jo has to build a flying balloon, Lightning must build a helicopter, Zoey must build a plane, Cameron must build a rocket ship and Scott gets to build a bird. To test the rings of fire if they are safe to fly through, Chris uses Heather as a test dummy to see if she survives the flight. Heather uses a jet pack and she does survive. While the contestants are finding and building their flying objects, Zoey is mad that Scott eliminated Mike so Zoey steals Scott's parts to build her plane, causing Scott to get nothing, just a pair of wings he got from birds. At the challenge, the five are ready to fly their objects through the rings of fire, but suddenly Heather gets mad and steals the million dollar case from Chris and then takes off on a blimp. The challenge is now to chase the blimp and capture Heather to take back the money. Everyone is now chasing the blimp and during flight Zoey gets to fly on radioactive flying goats that breathe fire, so then she gets to take her revenge on Scott by shooting fire at him. Scott also has to deal with more attempts from Fang to eat him, both on land and in the air. Lightning manages to get on the blimp, and then retrieves back the money case from Heather. The blimp then loses control when Cameron crashes his rocket into it and falls for a crash landing while Lightning hops out with the case, and then gives it back to Chris. The blimp now crashes into the ocean and sinks, and even though Lightning got the million dollars, it was Cameron who won immunity for crashing the ship and taking out Heather. In the elimination ceremony, Jo is eliminated. The final four are now Scott, Zoey, Lightning, and Cameron.
