Diababa is the boss of the Forest Temple, a giant plant monster. The battle takes place in two phases. In the first phase, use the Gale Boomerang to target the bomb-carrying Monkey and then the plant's head to make it swallow the bomb. Repeat this for both heads. In the second phase, a central eye will appear. Use the Boomerang to stun it with a bomb, then attack with your sword. Keep moving to avoid its attacks.
