The idea of using the corn as ammo for a weapon that forcibly fattens the hens (possibly to the point of exploding) is a great is great.
Ah, could also work as a "secret pacifist path" where you only feed hens until they're immobile but NOT pop them; the game doesn't really advertise this as a thing, but they count as being "defeated" even though they're technically not dead.
If you go the whole game without killing anyone, you get a secret good ending. If you kill EVERYONE, you get a genocide ending with a powerful final boss. Anything in-between just gives you a normal (probably bad) ending.
