Ty has trouble keeping all of the new Trux organized and cooperative, and D-Structs comes up with a plan that throws the crater into even more chaos.
To escape trouble, the Dinotrux make a raft and hit the sea.
Upon returning to the crater, the Dinotrux discover that D-Structs has taken over and built a huge wall to keep them out.
When the crew is forced to spend a night in the desert to avoid a sandstorm, they wake up the next day without their most important parts.
The Dinotrux investigate when all of the other trux in the crater start running away from a mysterious mountain that seems to be coming alive.
With the mighty Dreadtrux threatening to destroy the crater, Ty considers working with D-Structs to save both of their homes.
