Hippocrates, the new hamster that just arrived at the lab, is lost. Fortunately for him, there is Bacillus, a little mouse who knows all the ins and outs and takes on the task of showing him around. He will introduce him to the sick mice, the blind rabbits, the mutilated cats, and will lead him into the depths of medical research through scalpels, syringes, test tubes, and... uncontrollable laughter. Laughter amidst this horror? Yes, because Bacillus is not a lab animal, he is a prank animal. He never loses his cheerfulness, nor any opportunity for sarcastic teasing. In this album, Arkas delivers a true recital of black humor. If you're feeling down, read it. You'll see improvement.
