There's one nice subtlety that the writing added. This book is supposed to take place around the confines of The Muppet Show, so it seems that no one in the muppet cast has actually met Andy and Randy yet, and Kermit only seems to know how terrible they are from Piggy's memories. Had it taken place after Muppets Tonight, I'm sure they would have been a LOT more acquainted with how clumsy and stupid they really are.
