The World's Most Famous Made-Up Nonsense Word
- Next, Bert and Mary meet back up with Michael and Jane—who had been running around this whole time doing whatever. They ride a merry-go-round, and the horses jump off the carousel and carry them through the woods.
- Bert and Michael start racing with each other, before Mary makes them slow down.
- Animated foxhunters and hounds go racing by. They ride with Mary and company for a while, but Bert decides to help save the fox (who is apparently Irish—he speaks with an accent—getting chased by British foxhunters. It's a political allegory).
- Bert picks up the fox, and they ride onto an animated racecourse.
- The jockeys chivalrously let Mary pass them, and she wins the race. Cartoon men present her with a big bouquet.
- One of them asks her how it feels to win and Mary says it feels, "Supercalifragilisticexpialidocious!"
- Then, she launches into the song, "Supercalifragilisticexpialidocious!" while Michael and Jane stuff their faces with ice cream.
- When they finish the song, a thunderstorm breaks out and it starts raining. The rain erases the chalk drawing on the street, and suddenly Mary, Bert, and the kids are back in the real world.
- They part ways with Bert and head home.
