Something fishy is up and Nanny X, an agent for Nanny Action Patrol, and her young charges plan to investigate in this sequel to NANNY X, which was called "a fun and funny blend of Spy Kids and Mary Poppins" by Kirkus Reviews.
In their second adventure, eleven-year-old Ali, eight-year-old Jake and baby Eliza go fishing with Nanny X, only there is something odd about their catch—it's robotic! While the gang wonders about this strange occurrence, a robotic squirrel shows up and tries to steal Nanny X's computer, which is disguised as a box of baby wipes. Meanwhile, a mysterious person known as The Angler is threatening the nation's treasures if the president doesn't install a statue of a fish on the White House lawn. Nanny X wonders if these weird incidents are connected, and a series of investigations surrounding a jealous artist yields non-stop action and humor.
