There were rocks in the older gen pony shows. I am still working through my new g1 course packet, so I don't know exactly what kind of role they played, but I'm sure it was critical to the success of the series. Did you know Tom in particular showed up multiple times? He was their "Derpy", but none of them really picked up on it. Kind of sad really... So much potential lost.
Anyway, this awesome new TOM plushie has joined the ranks of epic g4 customs. Just look at those details! Seriously Hasbro, you need to pick up on this. I already broke five monitors trying to throw money at the screen.
