Trisha wont admit to her family that she has a crush on Mr. Rankin, nevertheless it is true that she helps the biology teacher out in the lab at lunchtimes cleaning the test tubes and cages. In the lunch hour, intent on doing a magazine article about the school animals, Judy visits the biology lab and finds Trisha there. Against her better judgement, Trisha lets Judy look at the grey school hamster, but it escapes when the bossy Miss Clark suddenly enters. Trisha earns a detention for her earrings. In trying to corner the creature, Trisha and Judy bring down a bookcase. Judy decides they can replace the animal, and Trisha remembers she has school holiday money.
