The numerical identifier “391” refers to a specific toy figure within the Littlest Pet Shop (LPS) toy line. This designation allows collectors and enthusiasts to precisely identify and differentiate one particular pet from the hundreds of others produced under the LPS brand. For instance, referencing this number eliminates ambiguity when discussing specific design features, accessories, or rarity within the collecting community.
Understanding these identifiers is crucial for accurate trading, valuation, and cataloging of LPS toys. The numerical system provides a standardized method for documenting each individual pet released. Recognizing this allows collectors to organize their collections effectively, facilitates communication about specific items, and aids in determining the historical context and potential market value of individual figures within the broader LPS market.
