- The Flip Flopper is an exciting twist to a playground classic. This bouncy seesaw combines safety and fun with companionship. Although this unit can be played on alone, the excitement increases exponentially when played on by two children. Each kid will stand on the rotationally-molded plastic seats, grab the powder-coat painted steel handle, and bounce to their heart’s content. The handle allows children to correct their balance – helping them to stay firmly on the cute crab seat.
