Insights

Released and retired in 2016 as a Duplo promotional item, Duck (30321) had a very short window of supply but used common Duplo elements and lacked exclusive molds, and its limited adult collector demand has left aftermarket performance largely flat.

Set Facts

The DUPLO Duck was available exclusively through a special offer on shop.LEGO.com and LEGO Stores from March 1 to March 25, 2016.
The set includes elements to build a duck.

About Duplo

The LEGO DUPLO theme was introduced as far back as 1969 and is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick. Like LEGO System, DUPLO also has subthemes that are often junior versions of System themes, like Pirates and Castle and licensed themes like Disney and Super Heros.
