A subspecies of the Tyrannosaurus Rex that has successfully repopulated the world today. The Y. Rex is prone to sudden random dinosaur-induced outbursts and often struggles to extend its arms with a ritualistic arm dance to increase the efficiency at which it captures its prey.

A specie that fails to capture any fish to sustain its needs with its short arms and therefore resorts to other tactics in an attempt to lure the fish into its trap with its bait.
