Rock-a-Stack is a toy by Fisher-Price for young children. It consists of five colored rings stacked onto a ring base.

Tin Toy

It is first seen in Tin Toy as one of Billy's toys.

Toy Story

Andy has a Rock-a-Stack, seen under Molly's crib in Toy Story.

Toy Story 2

Seeming to have outgrown it, the now-forgotten Rock-a-Stack was seen on Andy's shelf, as seen in Toy Story 2, now missing two rings (one was pulled out of the toy box during the Green Army Men's search for Woody's hat). Seeing this, Mrs. Davis took this out to be sold at a yard sale.

Toy Story 3

A different Rock-a-Stack is seen in the the Caterpillar Room at Sunnyside Daycare in Toy Story 3.


  • The colors of the Rock-a-Stack rings changed from the ones originally presented in Toy Story. The new colors shown in Toy Story 3 reflect the colors of a real-life Rock-a-Stack.
