This episode and the Connie Stevens episode were filmed at the same time, before the rest of the season, as sort of test episodes. The idea was to show these episodes to American executives as a way to sell the show into syndication in the US.
While very similar to the rest of the season, there are a few things that stand out in this episode, notably Kermit giving Juliet Prowse a Muppet likeness of herself at the end of the show. The only other time this happens is in the Connie Stevens episode. This was going to be a tradition but it was obviously short lived.
