The LEGO Bob the Builder licensed subtheme was part of the DUPLO theme and based on the British children's television series Bob the Builder. The theme ran for eight years with only a small number of sets released each year starting in 2001 and is one of the longest running themes. Most of the sets were based on the vehicle characters seen in the show with some DUPLO figures including Bob, Wendy and Spud.
2005 LEGO Sets
2005 shaped up to be a significant year for LEGO collections. Starting with the fact that LEGO System celebrated its 50th anniversary, we also saw a LEGO set designers change their techniques in set designing. 2006 marked the year that the skin color of the Star Wars minifigures changed from yellow to light nougat which also continued to various other future licensed themes. While this was a simple change, the value of sets saw high growth. 2006 introduced the LEGO City theme which replaced the Town theme, as well as Tiny Turbos under the Racers theme. However, in 2006 LEGO did discontinue Alpha Team and Baby.
