lol Animators make mistakes. There are a ton of color mistakes in the G1 cartoon. Hasbro has been pretty consistent with Rumble being red ever since his very first release. Hasbro seems to know they messed up in the cartoon & have been sticking with the original toy. Which is very rare in this day of "CARTOON ACCURACY IS GOD & EVERYTHING ELSE SUCKS". You have your stupid goofy looking coneheads & dumb looking human faces on Tracks, Trailbreaker, Omega Supreme, Jetfire, Bumblebee & a ton of others for cartoon accuracy, can't the few of us that prefer toy accuracy have at least one? Isn't it bad enough the cartoon ruined so many badass looking characters by giving them goofy baby Gobot human faces?
