The Super Scooper
The Super Scooper is an invention created by Whit. It was designed as an Automatic Ice Cream Sundae Maker.
The Super Scooper is only included in two produced episodes. Neither of which are in the "complete" series (Albums 1-56). The original episode that it was included in was in the album Odyssey USA (#13: “Bobby's Valentine”), which is only available on the Adventures in Odyssey Club. The other episode (#117: “The Trouble with Girls”) aired...but was never put into an album (besides the Lost Episodes collection) So the Super Scoop has been long since forgotten.
It is described as an invention that automatically creates ice cream sundaes in an assembly line fashion. At the end of line, a crane puts the cherry on top. When Whit tested it, it started on fire, and that's the last anyone's heard of it.
