Okay, there's this one thing that's REALLY buggin' me... my villagers will be "trying to push the boulder",but nothing happens! I know eventually they're gonna have to move that thing, but how do I motivate them?! HELP!!

You don't... you need to solve a few more puzzles first If you're really stuck check the VV General Guide or for a complete tell-all, check here

the gc does it when its ready the other villagers try but wastes all the time they use trying long time to get gc though
