22: Thorn Valley
The rats search the toy tinker's truck and find small, rat-sized tools and other supplies like wire and motors. They decide to live in a small cave near the Fitzgibbon farm so they can steal the Fitzgibbon's electricity and water. They develop "The Plan" while there. Jenner leaves after they decide on actually thinking about doing "The Plan". Mrs. Frisby also learns how much the rats have done at Thorn Valley.
