After the gang builds their own robot, MONTE, aka. Mobile Omnidirectional Neutralization & Termination Eradicator. Barry taunts them into a fight before the Round-Robin because there was no guarantee they would actually be able to fight each other during the competition. The fight was very one-sided and MONTE lost. The Kwipke Kwippler is only seen in "The Killer Robot Instability" and is never mentioned again.
