As of my last update in 2023, there is no record of a LEGO set with the number 5401 in the official LEGO inventory or recognized catalogs. LEGO sets are numbered and cataloged meticulously by the company and followed closely by fans and collectors alike. Its possible that there might be a typo or a mix-up in the set number youve mentioned.
LEGO produces a wide range of sets across various themes, including but not limited to City, Technic, Creator, Star Wars, Harry Potter, and many others, regularly introducing new sets and retiring old ones. Each set is unique, coming with distinct numbers to identify them. If youre looking for information on a specific set or theme, I recommend double-checking the set number or providing more details about the theme or description of the set youre interested in. This would help in providing accurate and detailed information about the specific LEGO set youre looking for.
