Snaggleteeth (Blue and Red): You can read about these guys in more detail from the description for the Cantina Adventure Set and in the Blue Snaggletooth prototype. Here is a great photo showing the metamorphosis Kenner had to perform so that Snaggletooth would be the way Lucasfilm wanted it. The red version is the corrected one.

Basically, they resculpted the legs and added hair to the hands of the original sculpting. Then they molded it in the colors you see here with the base color of the head being grey and the base color for the rest of him being red, of course. The rest is painted accordingly.
