Recently, I played around with a ROM of the NES game The Legend of Zelda, and I discovered a rather obscure NES behavior with Manhandlas, which most of you probably don't know about. When you kill a Manhandla with bombs, it occasionally drops bombs. However, it does not seem to drop bombs when killed with any other weapon. It's kind of like how, whenever you stun a Dodongo with a bomb blast then instantly kill it with the sword, it always drops bombs.
