Ick-Yak
From Teletraan I: The Transformers Wiki
An Ick-Yak, also spelt Igyak, is a large, reptilian creature that you would never want to get near, yet one which Kup seems to encounter every now and then. He's old because he's hard.

After escaping Galvatron's forces that had chased them from Autobot City, Kup sat down to tell the Dinobots about his experience with an Ick-Yak on Beta IV. Kup had encountered the Ick-Yak amid a dust storm of some sort, coming down a mountain breathing flame from its nostrils. In his haste to hear the "good part", Grimlock knocked over Swoop, though Swoop didn't mind, as he also wanted to hear the good part. However, Hot Rod interrupted, voicing that they should focus on trying to rescue their friends from Unicron. Only Galvatron's subsequent attack probably saved Hot Rod from being eaten by the Dinobots. The Transformers: The Movie
Later, Kup told of another encounter with an Ick-Yak on Dredd. The Ick-Yak was capable of both bipedal motion and walking on all six of it's limbs. Kup had managed to trick the Ick-Yak onto walking across quickmud, causing it to sink. Wheelie and Blurr were not as impressed as Grimlock. Chaos
