To get to Golbox Village you need to first get the power up to swing from purple lums. Next go back to the first level and go to the part where you have to climb(the one with the two walls close together). When you get up swing by the lum and you can get to the village. Here you place the crystals which unlocks stuff like a 4-player mini-game!
