Generation One cartoon
During Galvatron's attack on Autobot City, Kup remarked that the situation reminded of the battle on Alpha Nine. He was about to elaborate when Grimlock stuck his "noodle" in Kup's way. Grimlock asked Kup to tell him about the petrorabbits, but Kup threatened to give Grimlock petrorabbits. Obviously, Kup had forgotten to whom he was speaking.
