BALL MAN

BALL MAN has a body that is plastic and makes a noise when squeezed. The ball has holes in it to allow different attachments to be added to him (hands, feet, eyes, etc). The child would be able to change BALL MAN into different characters with different outfits.
The toy is very similar to Mr. Potato Head, where there isn't as much of a scientific principle that may be learned from it, but it is more of the customization and creativity that drives the product.
Construction costs would be low for the ball as well as the different attachments. It would be very durable and the ball would be able to be thrown as well. The pieces may be less durable but would be made out of strong plastic. The toy would be safe for children 5 and older, as the attachments may cause a choking hazard for younger children.
