Gargantuan 1 crashes and Col. Bud Manstrong survives and hailed as a national hero. He and the Ventures are then honored at the White House. But the ghost of Abraham Lincoln appears suspecting an attempt will be made to assassinate the President.

While Dr. Venture constructs his Venturestien Monster, Brock has an existential crisis and a parody "Scooby Gang" arrives, looking to solve a "Mystery". Hilarity, violence, tripping on some vine juice, and a general pissing on Scooby Doo.
