Heimlich, Dieter, and Chef, the three pigs, live together in one house. The "Big Bad" Wolf moves in next door, and Heimlich gets worried when Wolf accidentally drops some knives out of a bag. Heimlich continues to spy on Wolf and is shocked to discover that Wolf turns into a plump middle-aged woman whenever moonlight shines on him. This alternate persona of him is obsessed with catching the pigs and turning them into a meal, but whenever Wolf is out of the moonlight, he is ashamed and embarrassed of his transformation.
