This ride is based on the "dark scary" rides like "Mr. Toad's Ride" "Snow White" at Disneyland. The little car follows a circular route through the ride. The interior semi-circle is filled with all sorts of scary things like snakes and monsters.
The ride is powered by a Technic micro-motor pointed straight-up. This has an arm attached to it that supports the car from below. I wanted something with a more complex track layout, but the only thing available is LEGO train track and that's too big!
