Franny is a mad scientist, always cooking up strange things and serving up a portion of goofy horror in each book. Author Jim Benton is a cartoonist who includes large illustrations on each page and incorporates lots of visual games into his stories. Though the main character is a girl, these books have a sufficient grossness/mayhem quotient to appeal to the boys as well. Will appeal to kids who like Captain Underpants reluctant readers. Beginning chapter book.
