Cake and Pancake(Коржик и блинчик)

The hedgehog-inventor got tired of cleaning the house and decided to create a robot that would work on pancakes and do house cleaning. This is how the cat vacuum cleaner appeared. And everything was fine until the Hedgehog's dog ate all the pancakes prepared for the cat vacuum cleaner. A little more and the revolution of robots would begin. But the Hedgehog saved a friend.
