I forgot to take a before pic of the mods I did, so this pic only shows the re-paint work.

Basically I cut his jaw off and trimmed it back then glued it back into place reducing his severe underbite. Then I dremeled down the side and back of his neck reducing his rock collar and dremeled in new cracks to match th rest of his body. Thing's original color was bright Cheetos orange. I fixed it by washing him in Sienna Brown, dry brushed in Pumpkin Orange & Orange, clear coat in Tamiya Clear Orange, followed by another coat of dry brush Orange & two coats of Testors Dull Cote.
