90% of this episode is the same as "In the Dough" where Gumby and Pokey are invited to see how to make bread.
The framing story in this version is simplified, and the danger is less pronounced. The original one is a much better presentation, but might give young children nightmares.
As usual in the early Gumby show, the creators have a lot of fun with the animation, and a baking factory is a perfect setting for their imaginations.
