Nell is furious when she hears a squeaking noise coming from Joey and Matthew's room. When she checks in on them, she finds out that they are caring for Joey's class hamster, ""Harry"", who Joey knows would most likely be used to be tested on human products. Nell and Addy decide to make a fund to stop people from testing animals with human products. Late at night, to stop the squeaking of Harry's cage, Nell pours salad oil on it. However, what she doesn't know is that it is rancid. When she gets another hamster for Joey, she is surprised that it is a girl who has just had six babies, making Joey change his mind about her, after he finds out she killed Harry.
