Mad Scientists' Club

A strange sea monster suddenly appears on the lake… a fortune is unearthed from an old cannon…a valuable dinosaur egg is stolen. Who’s responsible? Those seven junior geniuses—and their wild ideas! "Every time you Mad Scientists get mixed up in something, it means trouble!" cries the mayor of Mammoth Falls. Watch out as the seven junior geniuses of the Mad Scientists’ Club turn the town upside down.

Just another quiet day in Mammoth Falls. Or is it? Have flying saucers really been sighted? How about those rumblings in the ground during the wee hours of the morning... and a midget submarine hidden in a secret cavern? With evidence like this, our seven young geniuses can't be far behind. And they're not! The town of Mammoth Falls will never be the same again, because here come the Mad Scientists with five more mad adventures!

The whine of jet engines thunders from above as the giant Air Force bomber makes its approach to Westport Field. Suddenly, the citizens of Mammoth Falls are startled to see the bomb bay doors open and an object drop down, down, directly into Strawberry lake. Splash!

It wasn't the diamond as big as the Ritz, but it was a pretty big chunk of ice, and it got the precocious pranksters of The Mad Scientists' Club entwined in an international intrigue only the intrepid investigators of Interpol could unravel. Take the seven young mad scientists of Mammoth Falls, stick them in an antiquated blimp bound for the Austrian Alps, along with two "hep" college girls and a zany professor of mysterious Rumanian origins—and you have the makings of a high-flying fun fest!
