설명
Steffi, Kenny, and Jose stumble on a quantum space-time dislocator--disguised as a port-a-john--which transports them to the time of the dinosaurs, just a few hours before a meteor will hit the earth--the meteor that rendered the dinos extinct! Graphing and other mathematical skills help the kids escape--just in time!
