Strategy: This boss battle is very difficult. Tateobesu can turn invisible, and the entire battle is played underwater. The only firearm you can use is your Bow Gun. Just have to repeatedly shoot at him with your bow gun. Also drop cranky bombs from the top, as it is likely that he will crash into those bombs.
- TAIL SLASH: Using his tail, he slaps you with it. Just try and stay as far away from Tateobesu to avoid any damage. It is hard to move in the water to avoid his attacks.
- BITE: He uses his mouth to bite you. Nothing much to say except stay away from him.
- INVISIBILITY: Tateobesu can turn invisible whenever he wants to, and it is impossible to lock on to him, and hard to see him.
