In a world where monsters can only be seen by a select few, allergy-prone Zick has the ability to see invisible monsters living among us, a handy talent to have when the creatures misbehave and need to be tamed. Taming monsters may not be an easy task, but these kids are committed to it. With some help from their cat, of course. Zick and his ordinary friend Elena must capture the mischievous monsters as well as the evil Magnacat.
