After returning to their home in Dullsville and finding it in absolute shambles, Jaundice and Kale Bland are rescued by high-flying aviatrix Beatrix Airdale. This time, they're jetting off (literally) to Egypt to uncover the mysteries of a magical scarab. By way of Casablanca, and after foiling multiple attacks along the way (thanks to Jaundice's nautical knot-tying skills and Kale's super-sleuth powers of observation), the Bland Sisters are reunited with their parents. But it turns out that Mom and Dad aren't as bland—or as Bland—as Jaundice and Kale remember. Thanks to their mother's old archaeology notebook, the Bland Sisters uncover their parents' real identities and help them achieve victory in one final family-filled adventure.
