Link probably should have done his research. He definitely should have done his research. He also should have brought a weapon. He'd driven to the beach to see the "movie set" and get a better idea of the world where Zelda worked, without spying on one of her own sets--that and he loved monster movies. But this clearly was NOT a set or anything mechanical. This was the real deal, no doubt having something to do with some unfortunate sap's dreams.
