A game in the JumpStart series of Edutainment Games. The plot is somewhat weird. An Uncle Pennybags/Omnidisciplinary Scientist character named Professor Spark for some reason lives in a Raygun Gothic Elaborate Underground Base built inside the mountain of the subtitle. His daughter Polly is a Royal Brat who may be best described as a Diabolical Mastermind version of Veruca Salt. One day, while the Professor is out, Polly fails a history quiz at school and decides the solution is to use Daddy's Time Machine to alter history, thus making her quiz answers correct. With the help of Botley, a Robot Buddy who serves as Polly's Badly-Battered Babysitter, you, the player, have to thwart Polly and Set Right What Once Went Wrong before the Delayed Ripple Effect will (supposedly) set in.
