Instructions
Assemble the four risers that support the elevated track. Snap the center piece between the two side pieces, which look like logs.
Arrange the Shake Shake bridge, which is already assembled, and the four track risers in an oval layout.
Snap a large curved piece on either side of the bridge. Continue the track by snapping the different sections in order. Press the track onto the riser when you get to that point, then continue until you form an oval.
