Sneak Peek at the Muppets' Musical Number on 'Good Luck Charlie' [Exclusive Video]

Yahoo! TV

It's so happening: The Muppets are taking Disney by musical storm for the "Good Luck Charlie" Season 4 premiere! Miss Piggy, Kermit the Frog, Fozzie Bear, Animal, and, yes, the chickens are popping up in Teddy's (Bridgit Mendler) dreams for a full-on song-and-dance number -- complete with feather boas and jazz hands. There's also some playful competition between the head diva, Miss Piggy, and Teddy's mom, Amy (Leigh-Allyn Baker).

This exclusive sneak peek at the musical number from the upcoming episode, "Duncan Dream House," also features interviews with Miss Piggy, Kermit, Mendler, and Baker. Speaking of dreams, having the Muppets on set is a dream for the cast -- particularly in Miss Piggy's opinion: "It was fabulous. Everyone was so warm and friendly. And naturally, everyone was absolutely thrilled to meet moi."

If you'll remember from the Season 3 finale, the Duncan house was in shambles following a termite invasion, and now the family must abandon their old digs and build their dream house. Sounds like a good deal, and everyone seems to be onboard -- everyone except Charlie (Mia Talerico) and the Muppets, who invade Teddy's dream to convince her that the family's old, bug-ridden home is actually her dream house. The episode's original song "Dream House" was written by Grammy and Emmy Award-winning songwriter and Fountains of Wayne bassist Adam Schlesinger.

The Muppets have been making the TV rounds for years, most recently appearing on "30 Rock," "Top Chef," "Jimmy Kimmel Live," and "The Bachelorette" during Emily Maynard's season; Miss Piggy was also both a judge and a client on "Project Runway: All-Stars."

Season 4 of "Good Luck Charlie" premieres Sunday, 4/28 at 7:30 PM on the Disney Channel.
