“Remember to take proper care of your teeth!”

—FLUDD, Super Mario Sunshine

Eely-Mouth's golden tooth revealed after Eely-Mouth is defeated, from Super Mario Sunshine

Eely-Mouth is a boss in Super Mario Sunshine. It is an eel dwelling in an underwater chamber below Noki Bay. Eely-Mouth's gingivitis is the cause of the widespread pollution in the area. In order to purify Noki Bay's water, Mario must clean Eely-Mouth's eight teeth, three of which are rotten and fall out after being sprayed with FLUDD's water. Eely-Mouth has two separate pairs of eyes on either side of its mouth; one side has a pair of eyebrows, and the other has long eyelashes.

At the start of the episode Eely-Mouth's Dentist, the Noki elder explains to Mario that he has finally figured out the problem as to why the bay is polluted, and sends him to the ocean floor to fight Eely-Mouth. In battle, Eely-Mouth is aggressive and spins around very fast, then it rises upward and opens its mouth, giving Mario a chance to clean its teeth by spraying water at it using FLUDD. After some time, Eely-Mouth sucks in water, and Mario as well if he is too close. If this happens, Mario is quickly spat back out and loses air. Toxic purple tears come out of Eely-Mouth's eyes regularly, and they damage Mario on contact yet refill his breath meter like regular bubbles. Once all the teeth have been cleaned, Eely-Mouth retreats back into its cave and spits out its golden tooth, which turns into a Shine Sprite. As Eely-Mouth recedes into its cave, it also leaves behind 20 coins in a heart-shaped formation, which float just above the mouth of its cave (collecting them is optional), most likely as a sign of thanks. After Eely-Mouth has completely disappeared, FLUDD comments, "Remember to take proper care of your teeth!"

In Mario Golf: Toadstool Tour and Mario Golf: Advance Tour, the name "Eely-mouth" can appear on the leaderboard.

Trivia

• Even if it cannot be seen in-game, Eely-Mouth's interior is fully modeled. This likely means that it was intended early in development for Mario to swim inside of Eely-Mouth, but this feature was removed for unknown reasons.
• If the game is hacked to get out of bounds, it can be seen that the back half of Eely-Mouth isn’t modeled, because the devs never expected the player to be able to see it. This can also be seen through a glitch that can randomly happen where Eely-Mouth will accidentally rise too high out of its hole, revealing the edge of the model where it cuts off. Going out of bounds also reveals that Eely-Mouth’s hole has no interior and abruptly ends past a certain point, revealing the black skybox of the Nooki Depths, which has strange yellow bioluminescent-like flashing lights, below.
• It is possible via a glitch to clip through Eely-Mouth’s body and end up partially inside of it, but a second invisible barrier prevents you from getting fully inside of it. This second barrier can also be glitched through, however. Doing so reveals a fail-safe mechanism implemented by the devs in the case you somehow got into Eely-Mouth’s body; upon getting inside it’s body, Eely-Mouth will lower itself down until you are inside of it’s mouth, in which case the cutscene for being eaten by it will play, and Mario will be spat out by it.
• One pair of Eely-Mouth’s eyes are masculine, with large eyebrows, while the other pair is feminine, with large eyelashes, meaning Eely-Mouth is potentially genderless. The male eyes release far more poisonous tear-bubbles than the female eyes do for an unknown reason.
• Releasing a tooth on Eely-Mouth’s female side will cause it to make feminine pain sounds. Conversely, releasing a tooth on its male side will cause it to make masculine pain sounds.
• Eely-Mouth, the Gooper Bloopers, Mecha-Bowser, King Boo, Giant Chain-Chomp, Bowser, and Bowser Jr. (only in the final battle) are the only bosses in all of Mario sunshine who do not splat into paint and die upon defeat.
• Eely-Mouth is by far the largest enemy, boss, and character in the game, with only Bowser, Mecha-Bowser, and Phantom-Manta coming anywhere close to it in size.
• If one were to take a very close look at Eely-Mouth’s eyes in-game or look at them through a model editor, a picture of a beta version of Ricco Harbor, complete with Mario and a few enemies, coins, and NPCs in it, can be seen reflected in them, despite the fact that Eely-Mouth isn’t fought in Ricco Harbor. This is likely because Eely-Mouth was originally meant to be fought in Ricco Harbor early in development, but this was changed at some point later on for unknown reasons.
• Eely-Mouth bares several similarities to the Unagi Eels present in several games, specifically the one in Super Mario 64, Super Mario Sunshine’s predecessor, as both are massive eels that live very deep underwater (only in Super Mario 64 for the Unagi Eel), are completely invulnerable to damage (Eely-Mouth’s teeth can be cleaned, causing it to permanently go back into its hole, but it cannot outright be defeated), and try to eat Mario to hurt him.
• Though it cannot be seen in-game due to its constant rippling, the waves of it being constantly thrown around, and the fact that it is constantly turning into bubbles, the goo inside of the cauldron Bowser and Bowser Jr. are fought in during the final battle of the game has a reflection modeled on it, as can be seen via viewing the goop in a model editor. This reflection is a picture of a beta version of the Nooki Depths, complete with Eely-Mouth in it. Strangely, in the picture, both of its pairs of eyes are quite far off center from where they normally are in-game. It is not known why this is, nor is it known why this reflection was even put here in the first place.
• There is an invisible barrier over Eely-Mouth’s hole that prevents the player from swimming into it after Eely-Mouth swims back in it once its teeth have all been cleaned and removed. This barrier cannot be glitched through in any way, but it is still possible to glitch through the crater around the hole to see the small parts of said hole that cannot normally be seen.
• Eely-Mouth’s fins are not fully 3D modeled, and are instead just moving Jpeg images.
• If you spray Eely-Mouth’s poison tear-bubbles for long enough, they will turn into air bubbles that will replenish your air meter.
• In all missions after it leaves, the waters of Nooki Bay will be clean and won’t hurt Mario anymore, the Nooki depths will be repopulated with Nookis (non of which can be talked to since Mario can’t talk to NPCs underwater), who have finally returned home again since the poison is gone, and Eely-Mouth’s hole will be completely covered up, with only the crater around it remaining. Swimming back down to the crater will reveal a hidden 1-Up for you to collect.
• It can be assumed the Bowser Jr., likely disguised as Shadow Mario, polluted Eely-Mouth with his magic brush, since it’s clearly in distress while Mario “fights” it, as it constantly cries out poisonous tear-bubbles, (which in turn means that it may not actually be intending to hurt Mario with its poisonous tear-bubbles, and instead does it because the poison causes it so much pain that it is forced to cry it out in tear-bubbles; if this is true, it is the only boss in all of Super Mario Sunshine with an attack it can’t control, an attack that isn’t meant to be an attack, and an attack that isn’t meant to hurt Mario), and it appears to be happy and thankful to Mario after he cleans and removes its teeth, as it leaves behind a large amount of coins in the shape of a heart after it leaves. This suggests the Eely-Mouth, despite its unnerving appearance, isn’t inherently violent or hostile, and is instead normally peaceful and docile, but it was turned violent and Hostile after Bowser Jr. corrupted it. This makes it the only boss in all of Super Mario Sunshine to be a natural creature native to Isle Delfino that was corrupted by Bowser Jr., as well as the only boss that wasn’t originally evil, and one of only two bosses that thanks the player upon its “defeat”, with the other one being Giant Chain-Chomp. This also makes it, along with Bowser, Mecha-Bowser, Bowser Jr. himself (only in the final battle), Giant Chain-Chomp, and (possibly) King Boo the only bosses in all of Super Mario Sunshine that weren’t creations of Bowser Jr. and his magic paint brush.
• Because of the nature of its “fight”, Eely-Mouth is the Only Boss in all of Super Mario Sunshine to never actually be attacked, fought or defeated; instead, Mario simply cleans and removes its teeth whilst avoiding its poison tears and its attempts to eat him, and once all of its teeth are cleaned and removed, it simply swims back into its hole and leaves a bunch of coins as a reward for curing it of its pollution.
• Eely-Mouth is the only boss in all of Super Mario Sunshine that is fought underwater. This makes it the only boss in all of Super Mario Sunshine where it is possible to drown whilst “fighting” it without the player having to go out of their way to do so. This also makes it the only boss in all of Super Mario Sunshine that straight up cannot be jumped on at all (because Mario obviously can’t jump underwater), as well as the only boss in all of Super Mario Sunshine where it is completely impossible for F.L.U.D.D. To ever loose any water from its tank whilst the player “fights” it without hacking, and the only boss in all of Super Mario Sunshine that cannot be “defeated” with F.L.U.D.D.’s tank at any level other than full without hacking.
• Eely-Mouth is the only boss in all of Super Mario Sunshine that Mario “fights” with the fish-bowl on his head.
• Because it is “fought” underwater to begin with, Eely Mouth does not react to being sprayed by F.L.U.U.D. at all. It will only ever react to it if its teeth are sprayed by it. It is one of the only entities in all of Super Mario Sunshine with this trait, with the only other ones being Petey Piranha Plant in his second fight while he’s sleeping and Giant Chain-Chomp after it is lured into the hot spring and cools off. Coincidentally, they are all bosses. It is also the only boss in all of Super Mario Sunshine that reacts to F.L.U.D.D. Only when a certain part of its body is sprayed, and doesn’t react to anything else.
• Eely-Mouth, King Boo, Mecha-Bowser, Phantom-Manta, Bowser, Bowser Jr. (only in the final battle), Giant Chain-Chomp, and Wiggler are the only bosses in all of Super Mario Sunshine that are only ever fought once in the game.
• The maximum amount of Eely-Mouth’s poison tear-bubbles that can be present on screen at once is unknown and cannot be seen in-game because the poison tear-bubbles pop before the limit is ever reached, so there’s never enough of them on screen at once for any new ones created by Eely-Mouth to be forced to despawn.
