While Heartstrong Flare and Calm Merriment may be alicorns and thus possess an alicorns, this does not mean that they can stomach such an amount of food. What with each one of these stallions having four stallions each within their heads further convincing them they could stomach the amount of food they consumed, and at a hayburger joint nonetheless. Only for the result to rather "stuffing" one could say. Least these two weren't drunk this time so if anything they won't be going anywhere anytime soon as the carb attacks these two guys are suffering from must be rather severe seeing as they just consumed 4 ponies worth of food each.
