Episode 30 opens with a situation that demonstrates the legitimacy of fearing the unfamiliar. On the Street, Ufnik attempts to shoo away Abigail by scaring her with words whose meaning she doesn't know. After a "Grapefruit Song" quicky, Abigail hosts celebrity Ronny Rock, and together they sing the nickname song "Mandelina". Bert fills up a bathtub for himself, and along with his Muppet friends, sings the song "I Gotta Be Clean". A boy named Ravid teaches Noah how to brush his teeth. Nuha's mother is a dentist, and in a local live-action film, we'll see how she visits her clinic for a routine examination. Returning to the Street, Abigail concludes that someone is planning a picnic in the park, on the basis of items she finds in the vicinity, but learns that it is important to base her conclusions on facts.
