A Run Cycle Through Time.At the request of Malcolm McDowell, Mystery Inc. travels to his estate just outside Santa Barbara, California in order to help solve the mystery of the Chronobeast and why it is pursuing him. While filming a Hollywood movie about time travel decades prior, he became deeply interested in the theoretical physics behind actual time travel in real life, cracking the code after many years of research. He escorts them into his secret underground lab before showing off his time machine which is made in the form of a pedal powered carousel featuring antique style "Big Wheel" bicycles on the outer track. Velma barely has time to get a call from her future self before the Chronobeast is hot on their heels, leaving the time machine as their only route of escape.
