ABC has debuted two new promos for "The Muppets," the first featuring Clark Gregg from "Marvel's Agents of S.H.I.E.L.D." and Randall Park from "Fresh Off the Boat," and the second with Miss Piggy in rare form.

As with the earlier TV spot starring Nathan Fillion, the one with Gregg emphasizes the more "adult" nature of the mockumentary series, as the actor transforms Park and Kermit's straightforward "back-to-back" promo into something awakward.

In the second, we get a glimpse into Miss Piggy and Kermit's fractured relationship, as the star of "Up Late with Miss Piggy" stumbles, and then unleashes her anger on her director/ex-boyfriend.

"The Muppets" premieres Tuesday, Sept. 22, on ABC.
