"Slimming Down! Go!" "Surimu de Gō!" (スリムでGO!) Aired: May 18, 1998
Having gained excessive weight, Gan-chan is unable to fit into his hole in the wall. Skuld and Urd help him slim down. Skuld tries several inventions, including Mr. Sauna, Mr. Icy Bath, and Mr. 4000 Years, but they all fail. Urd gives Gan-chan a pill that causes him to exercise. He exercises furiously and collapses, exhausted, after crossing the entire globe. However, they discover the next morning that Gan-chan ate gluttonously after this exercise and regained the weight.
