As of my last update in April 2023, there doesnt appear to be a LEGO set officially designated as “4131” in the well-known themes such as LEGO City, LEGO Technic, or LEGO Friends, among others. Its possible there might be a typo or confusion regarding the set number or theme. LEGO periodically releases new sets and retires old ones, covering a wide range of themes from cityscapes and vehicles to fantasy and space exploration. Each set comes with unique instructions and pieces tailored to recreate specific scenes, structures, or vehicles, sometimes including mini-figures as well. If youre in search of information on a specific set or theme, I recommend checking the official LEGO website or directly specifying the theme or detailed description of the set youre interested in. LEGO also has customer service that can assist with identifying sets if you have more information.
