Miss Piggy is furious that Kermit booked Elizabeth Banks as a guest on her late night talk show Up Late with Miss Piggy, Fozzie Bear meets his girlfriend’s parents, and Grammy Award-winning rock band Imagine Dragons performs their new single “Roots”.

In an attempt to make Miss Piggy happy, Kermit sets her up with Josh Groban who fills her head with ideas on how to make Up Late with Miss Piggy better. Meanwhile, Fozzie is invited to a party at Jay Leno’s house and everyone is annoyed that Bobo is selling cookies for his daughter’s troop.

Fozzie takes things a little too far when Kermit offers him advice and Nick Offerman steps in to help the gang. Meanwhile, Christina Applegate guests on “Up Late,” and brings Miss Piggy a sweet surprise that doesn't go over well and Pepe, Rizzo and Liam Hemsworth try to help Gonzo out with his online dating situation.

The gang has an epic night out when they run into Ed Helms at Rowlf’s Tavern and they all perform their favorite karaoke jams, but Kermit is not pleased when no one shows up to work the next day. Meanwhile, Fozzie has an unfortunate accident during the show.

Kermit is scrambling to find the perfect birthday gift for Denise, so he turns to Miss Piggy for help. Meanwhile, Kristin Chenoweth agrees to do a gig with The Electric Mayhem and inadvertently causes a rift between the band.
