In Mabe Village (where Marin and Tarin live and where the game begins), find a chicken and beat it with your sword continuously. After you take enough swipes at it, it'll call the cavalry, and you'll be savagely pecked to daeth by vengeful chickens! you can escape them by moving out of the screen and onto the next. This works with doggies, too, but they're more irritable and independant than chickens are.
