The Pet Defenders Code: 1. The safety of Planet Earth depends on you. 2. Humans MUST NOT know the truth. GOOD LUCK – you’ll need it… Biskit and Mitzy are confronted by a large alien spider who plans to destroy the planet. Worse, she has an army of nits that she can enlarge with a blast from her own invention: the Relativisor. She can also shrink things with it – and suddenly Mitzy is the size of a louse and clinging to Biskit’s head.  Can the Pet Defenders stop the nits ripping the Earth apart? It’s a head-scratcher!
