@Tuvae - What does it for me is the pure Looney Tunes-esque cartoon violence that shows up in it. A more specific example would be episode 15 where Twilight gets nailed with a flower pot, an anvil, a wagon, and a piano by Derpy. That one in particular is what drew me to it.
I dont get whats so popular about my little pony... Is there some kind of hidden meanings in this show? I thought it was a show for like 3 year old girls... Am i missing something? :O
