Age: Toddler-Preschool
Family: Older sister, younger brother

This sister and brother used to fight each other but now they fight crime. Wearing masks and capes for the duration of the book, Jinx and the Doom are seen saving innocents stuffies, fighting the dirt off their dog, and sneaking in lunch.

Although the book is small, this would make a nice read-aloud if projected onto the wall.
