I feel it's time to once again reiterate what Mattel has said about the reveresed forearms, since looking through this thread it seems that some folks have missed this.
Yes, the forearms ARE reveresed, and yes Mattel knows. According to Mattel, it was done on purpose. Here is the exact quote from Scott:
I just wanted to re-post this for anyone who may not have seen it in the other thread.“I checked with design and it actually was not a mistake but a deliberate way to differentiate Stinkor due to the heavy use of shared parts. Design discussed as a team and found that you could swap the gloves to create a slightly different look. They wanted to give Stinkor something extra since he is basically Mer-Man’s head on Beastman’s body and Mekaneck’s armor (even though we haven’t done Mek yet but you know what I mean!~). Much like painting Sorceress’ wings blue this was one way of making the toy pop a bit and be different on shelf. For reference, we also did this on BG Evil Lynn to much success!”
