The Return of Argor - S1.E27

The Dinosaurs and Chedra make Bullzeye a set of headphones so his late-night TV watching won't keep them up. But the headphones' Quadranian technology accidentally picks up a message to the Raptors - from Argor Zardok! Zardok has been in suspended animation, too, but now he's awake, and ordering the Raptors to find the equipment and massive amounts of energy he needs to return to Earth.
