Rhoga and Thudd

Rhoga and Thudd are the secondary antagonists of the animated movie Dinotopia: Quest for the Ruby Sunstone. Rhoga is a big-head Parasaurolophus, while Thudd is a dimwitted Euoplocephalus. Initially, serving as workers in a junkyard, Rhoga and Thudd's ambitions of "treasure hunting" led them to release the wicked warrior, Ogthar, out of his imprisonment, and since then they became his primary minions.
