| Synopsis | The crooks have hidden the Time Sphere and try to negotiate with Rip to help them find precious minerals to take back and make them rich in the present. In the midst of the discussion, the ledge they are standing on falls away and the bad guys plummet to their apparent doom. With no idea of where the Time Sphere is, Rip and crew have to set up camp for a possibly lengthy stay. But a volcanic eruption exposes the whereabouts of the Time Sphere and also puts it in danger of being destroyed. |

| Synopsis | As the time travelers make tracks for the sphere, they hear the cries of the crooks, who survived the fall and managed to accumulate a sack full of jewels. Since each sphere can only hold 4 people, Bonnie and Corky return to the present in one, while Rip, Jeff, and the crooks head for the disabled sphere, with the pieces necessary for its repair. Once the repairs are made, and the time travelers escape a dinosaur stampede, the sphere heads for its proper time. But home, the crooks find their sack empty, since one of the immutable laws of time travel is that you can't bring anything back with you from the past. |
