Inspired by the classic Fisher-Price Rock-a-Stack ring stacking toy, this wobbly drop-through activity toy introduces your baby to the fun of cause and effect! The Drop Through Rock-A-Stack comes with 5 colorful rings for little ones to slot through the top or side of the maze and watch as they roll down, around, and out the bottom. For added cause & effect fun, the maze features a wibbly-wobbly base, just like the original Rock-a-Stack toy! Colors and decorations may vary.
