 Reptar had been used since season one , episode three , " At the Movies , " as a satirical parody of the fictional Japanese monster , Godzilla . Despite being a green dinosaur , he still embodies the character , and though he is portrayed comically , his name is referent to the way a child would pronounce " Velociraptor , " made famous for its appearance in Jurassic Park , though that film is highly unlikely to have been the inspiration since it was released after Reptar 's début . Reptar is used to demonstrate and subsequently lampoon the ever growing domination of Japanese culture into children 's society .
