Bongo Bongo

Bongo Bongo is a mysterious cyclopean creature with two large disembodied hands. Once sealed deep in the darkness of the Kakariko Village Well, it is unknown the true origin of the beast. Once 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.

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 and travel across surfaces, and to manifest itself as a mysterious dark energy. 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.

When Link encounters Bongo Bongo, the battle occurs on a giant drum surrounded by a very poisonous purple slime (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.

If you play the game normally, it is the penultimate Temple boss to cross your path.

To defeat this beast, equip the Lens of Truth when it becomes invisible in order to see it, and avoid its hands when they attempt to attack you. Stun its hands with arrows to force it to reveal its giant eye protected by the flaps. Aim and shoot the eye with another arrow before Bongo Bongo tries to ram into you, then hack the eye with your sword. Once you repeat this process enough times, this evil will be no more.

Special: The ice arrow will also freeze a hand if hit.

A tip while facing Bongo Bongo, use your Hover Boots that you recieved from this temple to avoid being bonked back and forth from the drum.

Note the resemblance with the twili creatures, maybe they are related
