Many years ago, Professor Frankenstein revived a creature assembled from different body parts. The thing is, the creature called Monstro turned out to be not very quick on the uptake and mistook Professor for his Dad. So, for many centuries, Monstro has been looking for his Dad he’s unable to find. Peter and Wolf set to find Professor Frankenstein, assuming he’s invented the immortality elixir. Meanwhile, Monstro is acting like a child as he had no childhood and no dad around either.
