During medieval play time, Benny, dressed as a knight, is trying to build a sand castle, but whatever he does, it just won't stand up. As such, he has the "grrr" frustrations. Mr. Anthony shows Benny how to do the balloon to get rid of the "grrr"s. It helps, but it still doesn't solve Benny's problem of the constantly collapsing sand castle. So Mr. Anthony tells Benny about the time helped his knight friend Salim, who has a pet dragon, Smoky. Salim wanted to build a castle on top of a sand hill, but was frustrated because he went from digging the moat, to building the stone walls, to building the stone tower with the flag on top, each job unfinished leading to the tower falling apart upon what Salim thought was its completion.
