|Episode(s)||7.14 Plucky Pennywhistle's Magical Menagerie|
Libby is a waitress at Plucky Pennywhistle's Magical Menagerie in Wichita, Kansas. She has a son called Tyler.
Libby works hard, and often has to bring her son Tyler to work. When Sam is investigating the restaurant, he watches as she tells her son to do his homework as she has three more hours left on her shift. Tyler complains that he won't be able to concentrate because of the noise, but Libby just continues on with her work.
The next day, Libby is late for work, so gives Tyler money to take the bus to school. He leaves his sketchbook in the car with a drawing of his fear — a giant robot with laser beams shooting from its eyes.
Later, Libby walks over to serve Tyler pizza for lunch, which he says sucks. Dean approaches him and advises that he give his mom some slack. He then spots Tyler's drawing, and fears that the next attack will be on her. When Tyler's drawing is stolen, Dean encourages Sam to follow her while he investigates the basement.
