We've been having much fun with the Duplo Castle we pieced together from a few years ago. After seeing a cartoon drawbridge on the television, we were attempting to create a drawbridge. There weren't many options for a castle-esque Duplo draw-bridge. I sourced a few Duplo Technic pieces (after finding out there were Duplo Technic bricks), and we have constructed a draw-bridge for the castle. Complete with a moat for the plastic mermaid. Andre especially enjoyed driving the tractor and steamroller on and through this castle.
