The Thornberrys are in Tanzania, East Africa, near Mt. Killamanjaro. Nigel and Marianne are standing on top of the Communications Vehicle or Commvee for short. A bug flies up Nigels nose and they stop filming. Marianne states that the shot is missing something and Debbie their sarcastic sixteen year old daughter replies that lions were missing. Then Marianne realizes the shot needs movement. Marianne then muses how is she going to drive the commvee and shot at the same time, Debbie immediately volunteers to drive the commvee.Darwin expresses concern about Debbie driving, which Eliza comments that she won't talk to lions. Darwin responds to this by stating in a singsong that Debbie won't get eaten. Marianne gets done explaining to Debbie about everything about driving the ComVee, and Debbie replies that it's just like her grandma's (Sophie's) '64 (Dodge) Dart. Marianne gives Debbie an odd look before climbing down and begins to mutter some doubts. Once her mother is out of earshot Debbie remarks that it is nothing like the Dart. Debbie shrugs and tosses a wad of gum onto the floor. Nigel starts his monologue about lions and Debbie starts to drive, jerkily. They quickly come to the edge of a dry riverbed, and when Debbie tries to stop the Comvee, she can not as the gum was under the accelerator pedal. When the ComVee lands, Debbie reaches down and finds the gum. Marianne drops down into the interior of the Comvee as Debbie sheepishly comments they can 'try one for real.' As Marianne looks for a way to get the ComVee unstuck, Animals race out of the riverbed as the sky opens up and starts raining. A flood of water comes racing towards the Comvee and Marianne tell Debbie to get up to the roof, and pulls a cord that activates a pontoon. Marianne grabs a silver Emergency Case and climbs up to the roof as well.
