Bonk It is a toy.
History
Due to the long amount of time the family have to drive back from a ski trip, the Simpson children play it (while Marge attempts to hide the batteries). Later, Homer gets tired of it and throws it out the car, while another family throws theirs into the Simpsons' car by accident. Homer later crushes that one with his foot.
