The Long Road is the sixteenth mission in WorldBuilder.
Build a Forklift, grab the plans for the Gas Station, then build that as well. Grab the plans for the Treebot on the southwest side of the map, then go around the map and assemble enough blue and green bricks to build a Treebot; it is recommended you assemble them on the Energy Brick near the grove of trees at the beginning of the map. Be sure to park your Forklift near the Gas Station whenever necessary.
Uproot the tree on the southwest path near the beginning of the level, take apart the Gas Station, then carry the parts onto the goal. You do not need to worry about getting all of the red bricks to the goal; 25 red bricks and 5 green bricks will suffice. Once you have 25 red bricks and 5 green bricks on the goal, feel free to take apart your Forklift near the stack of bricks, and use the parts to rebuild the Gas Station on the goal.
