Приготовить про собственного возлюбленного героя-по англ Прошу вас

I would like to tell about Karlsson, my favourite character from a famous book written by Swedish author Astrid Lindgren. Karlsson is a short, stout, overconfident man, who lives in a small house on the roof of an ordinary apartment building. Karlsson has a button on his belly. When he presses this button, it activates a little propeller on his back. Thanks to this he can fly.
