Bongo Bongo

Phantom Shadow Beast: Bongo Bongo is a mysterious cyclopean shadow spirit with two large disembodied hands. Once sealed deep in the darkness of the Kakariko Village well, the true origin of the beast is unknown. After Ganondorf came to power, the beast was able to escape its prison within the well and retreat to the Shadow Temple, where Impa went to try to seal it again.

Characteristics
Bongo Bongo is noted as being one of the strangest bosses in the Zelda series. Some features that contribute to its oddity are its abilities to become invisible, to sink into a shadow and travel across surfaces, and to manifest itself as a mysterious dark energy (though the remake suggests these latter two abilities are the same). Despite its hands being separated from the main body, it still retains full control over them from a distance, allowing the creature to punch, slap, grab, and squeeze the life out of its victims. It also can shield its susceptible red eye by folding the flaps over it. It is also thought by some to be the hardest boss in the Ocarina of Time, even harder than Ganon. Some even believe it is the hardest boss in the whole series, while others believe it is easy due to the systematic way of killing it. Adding to this is the fact that Bongo Bongo has the highest amount of health of any bosses in Ocarina of Time. The easiest way to defeat Bongo Bongo is to have the Biggoron's Sword, which makes the fight much easier.

When Link encounters Bongo Bongo, the battle occurs on a giant drum (most likely a Bongo, given the name) surrounded by a very poisonous purple gunge (best to be avoided). Not only does it beat on the drum, but the creature sings throughout the battle with a strange voice much like the Four Giants in Termina.

Strategy
To defeat this beast, Link can equip the Lens of Truth when it becomes invisible in order to see it, and avoid its hands when they attempt to attack him. He proceeds to stun its hands with arrows (he can use other objects, as well) to force it to reveal its gigantic eye, which is protected by the flaps. If he doesn't have the Lens of Truth equipped already, doing so is key, as he sees the gigantic eye charging at him. Next for him is to either shoot an arrow while he's charging at him or to time it with another weapon. If Link doesn't time it right, Bongo Bongo can ram into him, causing damage resulting in the loss of three hearts. With good timing, he can then hack Bongo Bongo's eye with his sword. Once repeating this process enough times, Link wins over this evil entity. As a trick, if the young hero manages to complete several Quick Spins in succession flawlessly, he can effectively pin Bongo Bongo under his sword and defeat him in one down.

A tip while facing Bongo Bongo is to use the Hover Boots to avoid being knocked back and forth from the drum.

Origins
It is speculated that Bongo Bongo's hands are separate from its body because they were cut off as a punishment for stealing the Lens of Truth (which is found in the well, where its house used to be, if it is indeed the same person the old man was referring to), because cutting off the hands of thieves was a common punishment in medieval times. Its head also seems to have been cut off, suggesting it was executed, as there are guillotine type obstacles in the shadow temple.

There is some speculation regarding Bongo Bongo's appearance being somewhat similar to that of the Twili. Nothing can be known for sure, though there are some arguments against this since it is explicitly told that Bongo Bongo was sealed inside the Kakariko Well and not inside the Twilight Realm.

It is also thought by many fans that Bongo Bongo is a Shape Shifter, allowing it to take on any form, and that the one Link fought it in was just one of many that it chose from. The form Link sees it escaping from the well in (with Sheik while the village is in flames) is its "true form". It has an appearance slightly similar to Gohdan, and it is possibly based on a mutated Wallmaster.

An elderly person in Kakariko Village (located near the House of Skulltula) tells of how a man had the ability to see the truth, and his house was where the well is today (in the future). It is possible that Bongo Bongo is this person, as it manifests itself as having one great red eye, and the Lens of Truth is needed to see it. In addition, its eye bears a strong resemblance to the Lens of Truth. If Bongo Bongo is this man, then it is possible that the man was executed for some reason, given that the creature's hands are separated with stumps showing the flesh of its arms, and that its head is missing, replaced by a stump with the eye supposedly being its neck. It may have been executed for being a murderer, as both the Shadow Temple and Bottom of the Well are filled with undead and have various torture devices. Bongo Bongo may have been a powerful Sheikah (as the Lens of Truth, which is related to the Sheikah, is in his house, and it inhabits the Shadow Temple) who went mad and killed several people. The Sheikah then executed him and put the tear on the Sheikah symbol. In that same line of thought, Bongo Bongo may have also created the Mask of Truth, seeing as how the Sheikah symbol is found on it. The mask, defined as being powerful and unsettling, could be attributed to a powerful and eccentric or crazed creator, befitting of the character of the outlawed Sheikah who became Bongo Bongo.

Due to the fact that this battle is fought on a large bongo drum which Bongo Bongo 'plays', and that it seems to hum or chant during the battle, it is possible that Bongo Bongo was musically inclined in life.

Trivia

 * Bongo Bongo is the only boss in Ocarina of Time that does not actually require the item Link finds in its dungeon to be used during its fight. However, the Hover Boots can be used, but it is not a necessity for victory.
 * Bongo Bongo bears similarity to Andross, the final boss of the Star Fox series, from , and Master Hand from the Super Smash Bros. series, as they all incorporate large, disconnected hands as their primary means of attack. This tradition continues to internally spread within the Zelda series as well, apparent in the battles with Gohdan from The Wind Waker,  Ramrock  from Oracle of Ages, and Mazaal from The Minish Cap.
 * Bongo Bongo is one of the largest boss Link has ever fought, along with Molgera, Dark Dragon, Morpheel, Twinmold, Stallord, Cragma, Eox, and the Demon Train.
 * If an Ice Arrow hits Bongo Bongo's hand, it will freeze, and the other one will try to break it.
 * The song that Bongo Bongo sings during its battle is highly similar to the song that plays when the ghosts invade Romani Ranch in Majora's Mask.
 * Bongo Bongo "sings" the same rhythm as its drumming.
 * Bongo Bongo shares many similarities with Gabora from Majora's Mask: both don't speak but grunt, Gabora wears a mask filled with straw where Bongo Bongo has no head, Gabora wears gloves where Bongo Bongo has its hands separated from its arms, and official artworks show them with the same gray color and muscular body.
