Mechanism of "Earth Park !"

The rail track is the mechanism to revolve the "flowing pond". Set the wiring cords to two spots.

As you have to set a ship of Whale and a ship of Alligator on the "flowing pond", you need two controllers to send power.

Place a rolled pedestal on the center of the cover. This is a part to set up Panda and Elephant.

There are two holes for the wiring cords on the rolled pedestal.

Lay out the trains on the rail track. They are the parts to put the "flowing pond"/a ship of whale/a ship of alligator.

Each train for both whale and alligator has six carriages. In fact, five out of six are motorized carriages.
