Theo from the very birth reacts unusually to experiences: under the influence of strong emotions, the boy sneezes. This seemingly harmless feature brings Theo a lot of trouble – at the moment of sneezing, he turns into animals and cannot control his reincarnations in any way. Along with the appearance of animals, the main character also adopts their habits. This usually happens at the most inopportune moment, which leaves Theo and his friends Peter and Flo in funny situations.
