Rogers brings a ball float, which he will install in his toilet. When he flushes the toilet, the ball float stops the filling of the water tank. He fills his bathtub with water and pulls the plug. He recalls that his grandmother explained that people can't go down bathroom drains. Maggie Stewart arrives with a book on sign language. Rogers gives her numerical sign language for "143." They look at the book Signs for Us (unavailable), seeing the signs for hello, friend, splendid, book, fish, house, love and goodbye. Rogers asks that Maggie sign along while he sings Let's Think Of Something To Do While We're Waiting.
In the NOM, Grand-père speaks French with Lady Aberlin. She asks Grand-père if he has seen Purple Panda. Then she goes to ask the Platypus family. Ana Platypus has come back from a swim with Purple Panda, who wants to visit Westwood. Mayor Maggie tells Lady Aberlin that they have found Purple Panda. King Friday does not recognize Purple Panda with the mask and swimsuit on the outside (and Matt Meko on the inside). Lady Aberlin gives Purple Panda the polymorph package. He reads the "Do Not Open" message, then commits the cardinal sin of tossing it up. Everyone has to go on the search for it again.
Back in the television house, Rogers goes outside to show a wagon that a friend loaned him. Rogers invites viewers to pretend their favorite stuffed animal or toy is in the wagon. Mr. McFeely shows up with a videotape on how people make toy wagons.
