Ozma and Dorothy say something at the same time. Dorothy playfully calls out, "JINX!" Suddenly, Lion, Scarecrow, and Tin Man look somber. "Oh no, Dorothy! You can't say that in Oz, it really sticks!" Dorothy and Ozma have lost their voices! They try charades but are comically bad at it. The group must travel to the land of Jibber Jab and meet the YAKITY YAKS for the antidote.

Dorothy and her friends find a one-winged monkey who has run away from home. Dorothy feels sorry for the monkey and is determined to get him his second wing so she asks for Ozma's help. Ozma tries to use her magic to make him a wing, but they don't seem to be the right ones for this Monkey. The gang has to travel to Dr. Pipt (the crooked magician) to get the right wing. On the way home, the terrible Wheelers attack our gang. The monkey goes to save them, but in the process, he loses his new wing. He takes advantage of his lopsided flying to tie up the Wheelers. The monkey realizes that his unique abilities saved the day.
