The One-man Band is a Magic Item that can be used to temporarily befriend up to 9 Pigs or Bunnymen in close vicinity. It requires 2 Gold Nuggets, 4 Nightmare Fuel, and 2 Pig Skins to craft and a Prestihatitator to prototype.

The One-man Band is worn on the body and will drain the character's Sanity at a rate of 2 points per minute. Each Pig or Bunnyman befriended with the One-man Band will drain additional 25 Sanity points per minute. With the max of 9 followers, this means losing Sanity at 227 points per minute.

The device lasts for 3 minutes (6 game hours), degrading when equipped. Once a character stops playing the band, the followers will only stay loyal for a few seconds. Pigs and Bunnymen don't immediately stop following and doing the player's bidding, which means that the player should use it at short bursts instead of keeping it equipped constantly, to avoid big sanity drops.

The One-man Band does not draw Pigs out of their houses at dusk/night or Bunnymen out of their houses during the day.
