King Conga is a boss in Crypt of the NecroDancer. He sits on a throne guarded by two "conga lines" of Zombies. Defeat the Zombies, then conquer King Conga.
The fight takes place in a large room with several monsters from the Zone you entered from, as well as two lines of eight Zombies. The lines of Zombies act like snakes, traveling in a line and moving every second beat. If a Zombie is separated from the main line, it will become red and will be able to move every beat. King Conga sits on a throne at the top of the room and cannot be hit, except by a Dagger of Phasing.
King Conga attacks only when all the Zombies are killed, or when the player misses a beat. King Conga will chase the player, moving cardinally or diagonally every beat. Once hit, he will teleport to a random location in the room. He has two HP in Zone 1, three HP in Zone 2, four HP in Zone 3, and five HP in Zone 4.
Every eight beat is skipped in the soundtrack (7 -
1). This is harder to notice with the FamilyJules7X soundtrack (which plays some high notes instead), and easier to notice with the default (Danny B) soundtrack.
With faster characters (Bolt and Coda), for 16 beats, the 14 and the 16 are skipped (13 -
1 - 1 - 1).
Losing your Groove Chain before defeating all of the Zombies will also cause King Conga to leave his throne to attack, but he will teleport back to his throne unhurt upon being hit.
Using a high-tier Shovel or a Bomb on King Conga's throne will aggro him, allowing you to beat the level much faster than by killing the Zombie lines first. The throne is effectively a catacomb wall with a wall torch. The shovel must be better than Titanium for this to work.
