Gizmo (Superbook)

Gizmo is the tritagonist of the first "Superbook" series. He is Christopher Peeper's toy robot who only comes to life when the titular book, Superbook, takes him and the two children into a Bible story, whereas, it's also when he and Uri Peeper are sucked into a computerized Superbook in the second series. In the first series, Helena Van Koert did his voice, while Billie Lou Watt (who also voiced Christopher in both series) took over in the second series.
