Overview
Dropping the rings through the top or side of the maze sends them rolling down, around and out the bottom. The base is wibbly-wobbly, inspired by the classic Rock-a-Stack.
Cause and effect arrives with every ring that rolls out, and the wobble holds the baby's attention. The listing does not give size or material, and decorations vary by unit.
Who it's for
Parents of babies from nine months who enjoy watching things drop and roll will find the maze engaging. Those who want the original ring tower, or specific colors, should look elsewhere.

Performance notes
