Oh, I just checked. It WAS the battling seizure robots on that Simpson's episode.
What did the "choco-mattel etc etc robots" appear on?
Ah: Different episode!

64. Can I Get A Boo-Yah? In an attempt to seem less commercial (no thanks to the "Mattel and Mars Bar Quick-Energy Choc-O-Bot Hour"), Krusty and the network honchos come up with something more educational -- a Kids News show. Lisa is the anchorwoman, and Bart starts out as the sports anchor. "Bart Simpson telling you to lock the doggie in the barn, because here comes dodge-ball action! The shirts continued their domination over the skins today. And in schoolyard fights, the highly anticipated match between Kearny and Mr. Largo ended in a disqualification, for use of dog poo on a stick."
