The Flip Flop is a reproduction of an antique toy that we have. This is one of our anti-frustration toys (see Jonesey for the other one). The toy pulls along behind the toddler, and when the direction is changed, the toy flips over itself and keeps right on going. There is no need to stop and "fix it." Also a learning toy, the Flip Flop teaches the stacking/counting of 1-2-3. It is made out of birch and measures 12 inches in length.
