ABC's inventive cross-promotion continues, with the stars of the upcoming "Muppets" series starring in a spot featuring "Agents of S.H.E.L.D" star Clark Gregg.

Pepe the King Prawn, specifically, does his best to get Gregg to spill Marvel's top-secret plans for the upcoming season. Gregg remains steadfast in his silence, as a good spy should, though it takes the appearance of another Muppet to finally get the super secret agent some peace.

Turnabout is fair play, though. After all, it was Gregg who made "Muppets" star Kermit the Frog and “Fresh Off the Boat's” Randall Park uncomfortable in a previous promo video.
