Catching the school's runaway guinea pigs is not really giving Alex job satisfaction, but how can he find a bigger test for his and Jess's awkward superpowers? Jess is more worried about the bullied new boy, whose Mum runs the local animal sanctuary. To befriend him she gets a voluntary job there, but she soon realises that something is very wrong; the animals are terrified. People start reporting strange events: things missing, property destroyed, and the local squirrels have turned mean. The police have no suspects. It looks more and more like a job for Agent Alex.
