The Simpsons

Springfield reached LEGO in 2014 and 2015 with two houses, a Kwik-E-Mart and two full series of collectible figures. Every character needed a moulded yellow head with its own hair and expression, so almost nothing here shares parts with the rest of the catalogue, and the overbite, the hair and the eyes are what identify a figure rather than a printed face. Two series, a handful of sets, and then the licence stopped, which makes the roster fixed.

• Moulded yellow heads, one per character
• Two series of collectible figures
• A fixed roster from 2014 and 2015
