Several Muppet projects have been conceived of having "spooky" and "scary" elements. While a majority of them have never specifically been labelled as "Halloween projects," the themes and tones of them can be characterized as "Halloween-y." For example, even though Halloween is never mentioned in [[Episode 307: Alice Cooper|episode 307]] of ''[[The Muppet Show]]'', the episode aired around October 31st in most markets. This same logic has been applied to various projects categorized here.
