Ahhhh! It’s Kermit the Frog and Fozzie Bear hanging out with Teddy (Bridgit Mendler) in the season 4 premiere of Good Luck Charlie (April 28, 7:30-8:00 p.m., ET/PT). We must be dreaming. Well, actually Teddy is. When a nasty case of termites means that the Duncan family must build a new house, almost everyone is thrilled at the possibility of an upgrade. But Kermit, Miss Piggy, Fozzie, and Animal appear to Teddy in a dream to convince her that the old family home is really the house of her dreams.

Take a look a the exclusive clip below, which features Kermit singing the episode’s original song “Dream House,”  written by Grammy and Emmy-award winning songwriter Adam Schlesinger (“That Thing You Do,” “Fountains of Wayne,” “Tony Awards”) and produced by Schlesinger and Steven M. Gold (“Saturday Night Live,” “The Colbert Report”).

Coming up this season, Luke Benward, star of the upcoming Disney Channel Original Movie Cloud 9, joins the cast for a special six-episode story arc. He’ll play Beau, a charming teen  who knows a lot about bugs and captures Teddy’s attention after Bob hires him to help with the business. Also in the new season, Teddy and Spencer work at remaining good friends, PJ enrolls in cooking school, Gabe develops a crush on his new neighbor and the bug business isn’t so great for Bob. All the while, Amy juggles life as a mother to five, Teddy works on her college application process and Charlie celebrates turning four years old.
