This is a list of Dora the Explorer episodes that aired between September 7, 2008-August 15, 2010. This marks the last season for the original We Did It song. This was the first season to introduce a new cast for the younger characters like Dora and Boots just to name a few. The picture pop-up sequence reverts back to how it was from the 1st 3 seasons of the show and the checkmarks get placed each time Dora tells the viewer what places have been passed. Note: An asterisk signifies an episode lasting more than 30 minutes.
