Dylan and Cole Sprouse are to act as hosts of the special, which will feature a comedy sketch with Billy Ray Cyrus introducing his daughter, Miley, to the Muppets' Electric Mayhem Band.

Miss Piggy will be seen casting herself as the Jonas sister, then performing with the Jonas Brothers band, while Kermit the Frog lives out his dream of singing "Bop to the Top" from "High School Musical" with Tisdale.

Kermit, Miss Piggy and Gonzo also will drop by the Tipton Hotel, the setting of "The Suite Life of Zack & Cody," Disney Channel said.
