This started as a doodle of Fluttershy. I didn't know how to draw the lower legs so I put Rainbow Dash there. Then I thought, "what if I add Twilight over there, and Pinkie there, and Rarity can be barely looking at you while sipping tea because of all her sass, and best pony can go over here. God that spot looks empty. F it, just throw Spike in there."
Is that a kiss mark on Rarity's cheek?
