The Reference Desk/Aliens in Iceworld

Hello folks! I wonder if someone could help me identify those aliens which appeared (briefly) on Dragonfire:

The short furry guy interests me particularly because he looks so much like Zog, in fact, the ears are different, but otherwise I think he looks exactly like Zog. Even though Dragonfire predates The Ultimate Adventure by two years, I'm inclined to think it might be the same costume, in which case, it would be interesting to add this to the story notes for Dragonfire.

And then you have this green guy which looks so familiar... I have a strong feeling I've seen this creature somewhere else, but I can't pinpoint where. Does anyone know who that is?
