“Milo Murphy’s Law,” the Emmy Award-nominated animated series is coming back for another season on the Disney Channel. The series stars Weird Al as the voice of Milo Murphy and the second season will debut with a one-hour “Phineas and Ferb” crossover special on January 5th. The special episode will air on both Disney Channel and Disney XD.

The episode is titled “The Phineas and Ferb Effect” and it will also be available that same day on DisneyNOW and Disney Channel VOD. Both series hail from acclaimed animation producers Dan Povenmire and Jeff “Swampy” Marsh, who will reprise their “Phineas and Ferb” roles as Dr. Doofenshmirtz and Major Monogram, in addition to voicing time travelers from the future, Vinnie Dakota and Balthazar Cavendish, in “Milo Murphy’s Law.”

Povenmire and Marsh said, “The story arc of ‘Milo Murphy’s Law’ has been designed from the very beginning to lead us to a big crossover with all the ‘Phineas and Ferb’ characters. We’ve planted lots of clues and Easter eggs in the first season, and we can’t wait for the fans to see these two worlds collide.”

“The Phineas and Ferb Effect” follows Milo and his friends, along with their newly discovered neighbors—Phineas, Ferb, Perry the Platypus, Candace, Isabella, Baljeet and Buford—as they work together to overcome Murphy’s Law in order to stop a pistachio invasion. The “Phineas and Ferb” guest voice cast includes Ashley Tisdale (Candace), Alyson Stoner (Isabella), Vincent Martella (Phineas), David Errigo Jr. (Ferb), Dee Bradley Baker (Perry the Platypus), Maulik Pancholy (Baljeet) and Bobby Gaylor (Buford). Starring alongside Yankovic on “Milo Murphy’s Law” is Sabrina Carpenter and MeKai Curtis as Milo’s best friends Melissa Chase and Zack Underwood, respectively.

Season two guest cast includes John Ross Bowie and Cedric Yarbrough (ABC’s “Speechless”) as shape-shifting alien buddies, Loab and Khone; current and former NASCAR racers Rusty Wallace, Joey Logano, Ty Dillon, Ricky Stenhouse Jr., Erik Jones and William Byron as themselves; sports announcer Mike Joy as himself; and Hal Sparks (Disney XD’s “Lab Rats”) as conspiracy theorist, Chaffe. Throughout the season, Milo and friends will face more calamities and trouble as Milo’s new housemate, Dr. Doofenshmirtz, brings his own version of chaos to their unpredictable adventures. New episodes will air Saturdays on Disney Channel (7:00 a.m. EST/PST) and Disney XD (11:00 a.m. EST/PST).

In addition to Povenmire and Marsh, the “Milo Murphy’s Law” creative team includes director Bob Bowen (“Family Guy”) and “Phineas and Ferb” veterans: producer and director Robert F. Hughes; co-producer and story editor Scott Peterson; composer and song producer Danny Jacob; and writers Jim Bernstein, Martin Olson and Joshua Pruett. Joining the writing team for season two are Valerie Breiman (“Friends with Benefits”) and Marja Adriance (“The Secret History of Rock ‘n’ Roll with Gene Simmons”). The series is a production of Disney Television Animation and carries a TV-Y7 parental guideline.
