Soldier Sam is a little toy on top of the roundabout and the original guard of the roundabout. When the Roundabout moves, he marches up and down. When Zeebad was freed he brought Sam to life and tricked him into being his evil servant. Unknowing to both of them his heart was the third Diamond, which he lost in an attempt to stop Zeebad. Zebedee later gave him the third diamond so he could stay alive and he returned back to his place on the roundabout guarding it.
