It's a spooky October Season surprise as the Summer of Muppets returns from beyond the grave. The scariest combination of words in this Disney+ special may just be "corporate synergy" as MUPPETS HAUNTED MANSION plays more as a cross-promotional advertisement for a theme park ride than a natural fit for these beloved puppet characters, but hey - it's still the Muppets getting to do stuff, so it's all ok in our books.
