Where it came from
The Birthday Party Girl was released in 2018 as part of the LEGO Minifigures Series 18, a collection specifically themed around the 40th anniversary of the classic LEGO minifigure design. This series was unique because it celebrated the milestone with a festive party theme, featuring characters in costumes and celebratory accessories, reflecting the long-standing legacy of the brand.
Designed by the internal LEGO creative team, the figure features a distinct cupcake-shaped hat, a printed torso with a party dress motif, and a gift box accessory. The figure was well-received by collectors for its whimsical design and the inclusion of a rare printed tile depicting a balloon, which served as an intentional nod to the celebratory nature of the anniversary collection.
