Enhance your Too Many Bones experience by adding Ghillie the Scoutmaster, Nugget the Treasure Hunter, Tink the Bot-Builder and Gasket, the Hydro-Mech! These Gearlock Expansions each add a single playable character that can be used to swap out a character form the Core Set or Undertow, or used with Undertow's characters to increase the player count above 2.
