CyberToy

The CyberToy is a toy that both Arthur and Buster wanted from the episode Nerves of Steal. In the episode everybody owned a CyberToy. This caused Buster and Arthur to want the toy like the rest of the kids, so they stole it from Jim's Drug Store. They eventually returned the toy from the feeling of guilt, but they got caught, and Jim called their parents.

It appeared again, although an alternate coloring, as a background prop in The Long Road Home. It is unknown how Arthur got this one. When wind from Arthur's open window rolled a pen onto it, the toy activated and walked forward, knocking over El Boomerang's box, causing the ball to be lost again.
