Rock-a-Stack

Rock-a-Stack is a toy by Fisher-Price for young children. It consists of five colorful rings stacked onto a ring base. It is first seen in Tin Toy as one of Billy's toys. Andy also has a Rock-a-Stack, seen under Molly's crib in Toy Story. Seeming to have outgrown it, the now-forgotten Rock-a-Stack was seen on Andy's shelf in Toy Story 2, now missing two rings. Seeing this, Mrs. Davis took this out to be sold at a yard sale.
