The Energon Pub

I just got my Titans Return Trypticon yesterday, and given the recent obscure continuity nods on the toys, (such as Seaspray with "Alanna" written in Cybertronian script on his arms) I was wondering if there were any similar little fandom features anywhere on Trypticon.

Given the size of him, there's a LOT of area with lots of nooks and crannies for hiding obscure details.

Has anyone found anything noteworthy? Is there a hatch labeled "Conversion Cog: Do not steal" somewhere on him that I've missed?
