Kim, Kate and Kylie find themselves in Transylvania, Romania on their way to a concert. As luck would have it, their vehicle breaks down in the middle of the spookiest region the world has to offer. It's not Dracula they have to fear here though; after taking refuge in an old castle, they meet the mad scientist Dr. Frankenstein who has a nefarious plan for the girls. His latest creation is that of a Mummy 'popstar' named Bunny who he has managed to make an exceptional dancer - but her singing voice leaves a lot to be desired. Thus, Frankenstein decides to steal the voices of K3, which doesn't bode well for their next performance.
