Disney Channel stars are breaking out their detective gear for “Whodunit” Weekend—and on Austin & Ally that also means some groovy disco outfits.

In Sunday’s episode, “Mysteries & Meddling Kids,” Ally’s (Laura Marano) songbook goes missing at the school’s ‘70s-themed party, prompting Scooby-style efforts to crack the case.

It’s just one of the mystery-themed episodes lined up to debut during Disney Channel’s themed weekend. Things kick off Friday with Jessie—when Bertram’s new toupee goes missing—and carries on through Girl Meets World, I Didn’t Do it and Dog With a Blog (Avery has to track down the culprit who ruins her latest design before the  big fashion show.)

The mysteries start up again on Sunday with an episode of K.C. Undercover, during which the search for a missing socialite interrupts the Cooper family vacation, and continue through the rest of the Sunday night lineup. So … whodunit? Tune in to find out. (A full schedule of the weekend’s episodes is available here.)
