Now that they've returned from the Uncanny Valley to find their home in Dullsville in absolute shambles, Jaundice and Kale 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.
