In Sledvaya, the sickest city of Tsamonia, a highly gifted scratchy (a very smart talking Tsamonia cat) named Echo finds himself in incredibly difficult situations after the death of his owner. He is forced to enter into a fatal contract with the horror master and dark magician Succubius Ispin. The contract gives Icepin the right to kill the scratch on the next full moon and use its fat for alchemical experiments. As a reward, Icepin must feed Echo at the highest level of culinary art during this time. But the horror master did not count on the will to live and the ingenuity of the scratch, and above all on his new friends - the Thinking Eggs, the Golden Squirrel and the One-Eyed Owl, the Boiled Ghost and Itsanwella - the last horror of Sledvaya.
