I have started to look into the 3rd Party Figures of the Dinobots and noticed Fanstoys has Grimlock's head facing in the opposite direction to what the original G1 toy can do. So I am coming to the Cartoon Thread to ask which is more show accurate? I know in S.O.S. Dinobots we had the head facing the Fanstoys' direction, but I feel the rest of the series stuck to having his head in the direction of the G1 toy.

Are there other moments in the cartoon that show off the back of Grimlock besides the first episode he debuted in?
