It's easy to see the fun here! With the sturdy plastic hammer, kids pound the colored balls into the four holes and watch with fascination as they roll down the ramp, make the colorful wheel spin and exit out the front hole into a trough. Your active toddler will have entertainment for a long time. The stimulation of the hammer and the tubes will not only help with hand to eye coordination, but will provide tons of enjoyment as well. The Pound A Ball game is a must have for any active toddler.
