Looks like Community is continuing its trend of producing epic concept episodes. The next one we can expect, according to cast and producers at the show's PaleyFest session? An whole episode featuring the cast as Muppet-like puppets. 

The episode will air in April, and, in addition to the puppets, will feature former Seinfeld star Jason Alexander as a "friendly mountain man." Not much in way of plot has been revealed, but we do know that it will surround the study group feeling awkward around one another after some time spent together in the woods so, per Dean Pelton (Jim Rash)'s suggestion, they recount their experience with the use of puppets.

Some other things to expect from upcoming episodes:

It's father time: Thursday's Thanksgiving episode marking the introduction of James Brolin as Jeff Winger's father will be "intense," McHale said. "It ends up being pretty heavy." Workaholics star Adam Devine plays Jeff's younger brother. Guarascio added that the story felt like "years in the making." (On a semi-related note, a fan said if Brolin, who guest starred on Castle as Richard Castle's father, is Jeff's father, does this mean Castle is Jeff's half-brother? "If there is a season five, we end up on Serenity," McHale deadpanned to major applause. "That was a nerd-jaculation.")

The origin story: An episode focusing on how the study group came to be will shed light on the time before we were introduced to the Greendale gang. Guarascio teased that viewers will go back to "how it came to be." Expect Annie's boobs (the monkey) to make a cameo.

The Dean writes an episode: Rash, an Oscar-winning scribe for The Descendants, penned an episode that pays homage to Freaky Friday. McHale called the episode "one of the best we've ever done." It will feature besties Troy and Abed, with a heavy body-switching element.

More Shirley: Brown teased that there's something coming up that's "bigger coming than Malcolm-Jamal Warner playing my husband." Let the speculation begin.

NBC hasn't canceled Up All Night, and yet this show is constantly on the bubble? What is wrong with the world?
