Penny is going to the national speech championships, and she's totally stressed out! So Rudy and Snap take her to the newest NightZone act, called ""Mother Tongue"". In this act, a clever, comedic female zoner called Mother Tongue licks the people in the audience. Once they're licked, they speak nothing but jibberish! When licked, Penny goes into panic and runs back home. But she forgot to get an antidote lick back from Mother Tongue! Now Rudy and Snap must get Mother Tongue back to Penny to give her the antidote before her speech in the competition turns to jibberish!
