Becky, Bob, TJ and Johnson are spending the day at the city water park... right after Mrs. Botsford finishes her seemingly unending list of errands. As the kids follow Mrs. Botsford to the bank, the grocery, everywhere but the water park, TJ and Johnson amuse themselves by imagining what WordGirl would do if a villain were to suddenly appear. Little do they know, their crime fighting knowledge will be put to the test when they finally arrive at the park.

Granny May is the star of her own advice show called "Granny's Corner", and though her advice sounds innocent enough, it has a way of inciting chaos around the city. WordGirl knows Granny May is up to something (she always is), but how can a couple of pieces of bad advice be criminal?
