hiya type in this order 34215 hope that helps

I just completed the theme park to light the led panel push in this order 34215. It will
light it up. Then go back to the ride part and put the wheel on the cart. Go into the
other building and place the bent nail in the vice grip and hit it with the hammer then
take the nail back to the cart and put it on the wheel. then hit it with the hammer and
then pull the lever. Hope this helps you.
