Lightbulb Tuchkin and the Bubble of Wishes

The school life of Lightbulb Tuchkin turns into fantastic adventures. He travels from the past to the future, from the future to the past — without the help of any time machines. How? He doesn't know either! There is a... fairy and there is a huge soap bubble, inside which Lightbulb's wishes come true, but for some reason they are always a little different from what he wants.
The adventures of the seven-year-old boy begin in the first grade, where he doesn't like it at all. Scribbles and writing practice, boring examples, mandatory reading — there was nothing like that in preschool, just play! "If only I could go back to that happy time," Lightbulb thinks one day, and together with his cousin Rodka, he comes up with what seems to be the perfect plan.
