Doc McStuffins is a DUPLO theme released in 2015 based on the Disney television show Doc McStuffins. The show follows the title character as she practices being a doctor on her toys. Three sets were released and the subtheme was discontinued in 2016.
The LEGO DUPLO theme 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.
