The white spots on pony eyes in this art style are supposed to represent light reflection on the eyes, not the pupils/irises. Although I suppose a flib here was okay to illustrate where the characters are looking, and to illustrate the strabismus.
My favorite animator vs. animation was when the stick figure noticed that he was in Teh Park and asked where the rides were. The animator was all, "No rides for you; this is Fighting Park." And when the stick figured asked who was fighting, the animator said, "You and me." Then the sky got all dark, and the stick figure got impaled upon rock spires that very suddenly jutted out of the ground. He accused the animator of cheating.
