Episode 5 is the 5th episode in Series 1. It originally aired on 8th March 1978.
Trisha Yates won't admit to her family that she has a crush on Mr Rankin, nevertheless it's 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. Judy runs to buy a hamster from the nearby pet shop while Trisha tidies up the lab. At the shop Judy is accidentally sold a white hamster instead. While Trisha frets, Judy runs back, almost waylaid by Jackie Heron's gang. The wrong colour hamster is put in the cage as Mr Rankin returns, and the original hamster makes his appearance. The girls confess - and an amused Mr Rankin points out the replacement animal is not only the wrong colour, but also the wrong sex! The biology teacher refunds Trisha's holiday money. As they go to registration Trisha suggests Judy writes about Miss Clark for her article about animals - because she is a cow!
