(Okay, technically, it's The Adopted Brother of Catzilla! But Son of Catzilla! just sounded better.)
Our story begins innocently enough, in a typical suburban house, on a typical suburban street, in a typical suburban town, on a typically quiet Saturday morning...
Until... something dark and malevolent is awakened inside of Felix, adopted brother of... Catzilla!
And suddenly no one is safe from his wrath. Run for your lives, little Iwako Japanese hamster erasers!
Oh no! It is too late.
