Cacophonic Conch

The Cacophonic Conch is an item that appears in Sonic Lost World. It is a very rare conch shell based on a real-life musical conch. When blown into, the conch produces a low-pitched sound that affects a nearby Zeti, naturally inhibiting their powers, but causing them great pain in the process as the frequencies it emits are very excruciating to them.

History

Prior to the events of the game, Dr. Eggman acquires the conch from an unknown location and uses it to enslave the Deadly Six. Whenever the Zeti fail to do a good job or try to speak up against him, he inflicts pain on them as punishment. When he tries to punish the Zeti for their failures at Desert Ruins, Sonic intervenes by kicking away the conch into the distance, never to be seen again for the rest of the game. This would be a terrible mistake, as it allows the Deadly Six to take control of Eggman's Badniks and rebel against the doctor.

It is implied that more than one Cacophonic Conch exists in the world, as Eggman vows to find another one to take the Deadly Six under his control again at the end of the game. However, the Japanese script suggests that the conch may be the only one of its kind as Eggman does not mention there being another.
