Something for all you wow nerds trucking away at it like me here. At the end of one of the quest lines in the new expansion, I (and several others of you if the submit box is any indication) ran into this drake with the name "Raindash". Blizzard's pony references have always been pretty subtle, with Pink Poeny (below) passing out sweets in the last expansion.While it could be a coincidence, considering this thing changes to all sorts of rainbowy colors, It's probably legit.
Heres to hoping more pony appears!
Now back to grinding this warrior up.
