In the playground, Lawson and Gelman were bored.
Lawson: I'm bored, I wish there's something I want to do.
Gelman: Me too.
Lawson: Hey! Why don't we sing a song about Miss Finster? It's called Pop Goes the Finster! It's inspired by a song from Thomas the Tank Engine called Pop Goes the Diesel!
Gelman: Good idea, Lawson! Let's do it! But first, we need to invite all our friends.
Lawson: That's a good idea.
Then Lawson and Gelman invited all their friends including Mundy, Skeens, Lazy Kid, Sue Bob Murphy, Kurst the Worst, Koreo, Jocko, Buster, Cheay, Chucko Kowalski and Clyde Philmore.

Kids are waiting in the playground; tackling them with ease'll. "Show the world what I can do," Gaily boasts the Finster. In and out she creeps about, like a big fat weasel. When she barges in and about – Pop goes the Finster!
