Ashu, an 8-year-old boy, feels lonely since his parents, Aditya and Aarti, don't have time for him, and he doesn't have any friends. As the story moves on, Lord 'Ganesha' becomes his friend, and together they resolve so many problems around and have a lot of fun.
Aarti and Aditya are too involved in their daily lives and hence cannot give much time to the boy, who always feels lonely. He would only get to be with the maid. On one rainy day, the boy saves a drowning mouse. He brings the small mouse home and tells the maid about it. She is very happy and tells the boy that he has saved Lord Ganesha's pet ride. Gangubai explains to him the full episode of Lord Ganesha & Mushakraj and also that he is his friend. Ashu gets sad and tells Gangubai that he is also alone and needs a friend, on which she tells him that Ganesha can be his friend. The boy gets excited at this thought. It was a period when the family was going through a crisis and was coinciding with the forthcoming Ganesha Festival. Gangubai somehow convinces everyone to bring Ganesha home for this festival. Ashu is very excited. Ganesha comes into their home, and things start turning around in their family. Ganesha becomes Ashu's friend, and together with him, they solve various problems in their family and have a lot of fun these 11 days.
