The Maretime Bay Amphitheater has officially been built, so musicians have an official place to perform in Maretime Bay. But the good feelings don't last when the ponies are sent away on an important and musical mission.

Scooby-Doo and the Mystery Inc gang team up with the Mane 6, the one and only rock-and-roll band KISS and four princess bat pony sisters in an all-new, out-of-this-world adventure! The Mane 6 reunite with their friends at KISS World, the all-things KISS theme park, to investigate a series of strange hauntings. With the help of KISS and their royal bat pony friends, they discover that the Crimson Witch has returned to summon the Destroyer from the alternate dimension of Kissteria!

The ghastly duo's plan? To destroy the Earth and any other realm they come across... including Equestria!

Can the gang's cunning, the ponies' magic and KISS's power of rock save the day? Tune in to this rock-and-roll mystery for some thunderous, heavy metal fun!
