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.
1990 LEGO Sets
In 1990, LEGO released several new sets and themes, including the LEGO Pirates theme, which introduced models of pirate ships, islands, and treasure. 1990 was also the year that LEGO introduced the LEGO Fabuland theme, which was a line of sets featuring anthropomorphic animal characters living in a fictional town. The Fabuland theme was targeted towards younger children and was popular for its cute, colorful designs.
