Which episode of Dragon Ball is this picture from? Why haven't I seen it?

This one is a fan, exaggerating the degree of H, but there is actually such a plot, when I went to my mother-in-law's house, when Yamcha hit the invisible man. Using Master Roshi's nosebleed to see the invisible man Ashu, Kulin only took off his coat. The first movie of Dragon Ball is mainly funny, supplemented by fighting. Because Toriyama Akira's character has a little H, there is nothing to make a fuss about. Besides, this painting style is nothing like the original. . . Typical fan diagram
