.. How to get Goal?

Really? Nothing big and metallic comes to mind?

Well, the crane, of course. Climb into the crane.

There is that maintenance box.

Throw out the defective fuse and replace it with a working fuse.

The crane works but you can't drop Goal into the void. Get the Mine Bike under the Funnel.

Go ask Doc for help and lift Goal into the Mine Bike.

Drive to the right and the go up to the Control Room. There is a skippable minigame about finding the correct route.
