Super Mario Sunshine Episodes

I still, at least 15 years after I played the full game for the first time, have nightmares about Eely-Mouth. The way you slowly descend towards a giant monster in the bottom of the volcano that gapes its mouth open to swallow you whole. Absolutely terrifying. Maybe it wouldn't be so bad if you knew how big the creature actually was (Morpheel from Twilight Princess comes to mind), but you never see anything but the top half of eely-mouth, meaning you don't know how truly massive this creature is. What if it's full body is bigger than the volcano you fight it in? You'll never know. On top of all of that, you're underwater, meaning you're at a disadvantage since you're mobility is severely weakened, whereas eely-mouth thrives and has much better mobility underwater. I have zero clue why this boss is not talked about more. this is easily, in terms of raw scare factor, the most terrifying thing I have ever seen in an E rated game.
