This Japanese series (Tondera House in Japan) aired on the Christian Broadcasting Network alongside another religious cartoon, "Superbook". It covered various stories from the New Testament of the Bible. The two main characters were children who stumbled across a house in the woods where they found Professor Humprey Bumble (in Japan, Dr. Tokio Taimu), his robot, and the professor's time machine. An accident involving the time machine, sends the house and everyone in it back in time where they experience biblical events.
Though often confused with Superbook, these two were completely different series. They did, however, share many of the same English voice actors.
