Dorothy and the Wizard of Oz S01E11 - Jinxed

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.
