Double Fine's Kinect-powered Sesame Street: Once Upon a Monster has a new downloadable chapter available starting today, "Unidentified Furry Objects." Oddly enough, today's letter is F, as Xbox.com is currently listing the DLC as free of charge. Previously the DLC was priced at 400 MS Points. Update: Microsoft has confirmed the DLC is indeed 400 MS Points ($5). The free listing on Xbox.com refers to a gameplay trailer for the DLC.

In "Unidentified Furry Objects," the Sesame Street gang greet some extra-terrestrials who land on Earth and then help them on a special mission -- well, the gang save for Oscar. We're pretty sure he's not the best ambassador for the block, you know?
