Scrooge and Launchpad enter Chickaboom Crag in order to find treasure. Once they discover a large gem, the Beagle Boys ambush them. Since taking the gem sets off deadly booby traps, Launchpad whisks Scrooge to safety and they leave with no treasure.
Scrooge is upset until his nephews tell him of the Flabberge egg, a jewel that had been reshaped by the royal Alexpanthers. They go to Paris, where they learn that a poor Alexpanther asked a dealer to sell the egg. The dealer discovered that no one lived at the address where the egg was delivered. When they search their books for the address, they discover that the address has been stolen. Launchpad follows a lady in a cat suit but loses her. When the adventurers learn that the cat lady is a dancer, they attend her show, but she is kidnapped before they can ask her questions.
