Kurdock is a giant, fire-breathing monster that has been terrorizing the planet of the Ultra-Cadets.
The Ultra-Cadets searched for Coop to ask for his help to save their planet. Jamie (pretending to be Coop at the time) went with them to their planet and they let him borrow a (pink) giant robot to fight the beast. In their fight, Jamie comically ran from the monster and led it to the foot of a volcano, where it accidentally slipped off before it could finish Jamie. The Kurdock later rose from the volcano and continued to wreak havoc at the end of the episode.
