I listened to the podcast episode where It's the Muppet Show was discussed, and I looked at the scans of the book. I remember reading it a long time ago, but there are only two things in it that I remembered (the cover, and the page with Sweetums, a Mutation, and Thog). Nothing else even rang a bell. I've read some of the Sesame Street books in this collection, and saw that this was the only Muppet book listed as part of the collection and figured that this was it. However, I did a search and realised that Muppet Wiki doesn't yet have an article about the book. I wanted to start one, but it was hard for me to read the words in the scans. What is the basic plot of the book?
