Find them and rebuild the catapult (simply toss each part at it) Once the catapult is rebuilt you are going to "Smoke" Cranky out of the hut (he is inside cooking) To do this you are going to close the 4 windows of the hut using the catapult and snowballs. There is a broken catapult nearby and it's 5 missing parts are scattered in easily identifiable places around the yard. Unfortunately Cranky has the crane key inside the logging hut and won't come out and give it to you when you knock on the door. The Catapult Operation & Getting the Crane Key Here you will find the road you need to follow to continue your journey blocked by a stack of logs that will need to be moved by a locked crane. Follow the fence until the area opens up - and then going to the right of the screen, head towards a bridge to cross over (jump the gate arm)into the logging yard.
Follow the path of these ramps until you come to a flat area with wooden fencing. You will navigate a small canyon with hollowed-out log ramps. It will take you to where you will need to finish the trip on foot. You are going to take the plow as far as you can towards Planks' Logging Yard.
You leave the Chalet and head back down the road to Wyatt Junction (where the mystery machine is parked and Moose's shop is at) You will find the snow plow to the left of the screen. The Ice Caves can be found by following a fairly long quest through Howling Peaks to get to them.
