There were actually two actors who played King Tut. It was in the Dr. Cassandra ep of season 3 they had the other Pengy and Tut.
The strange third season ep where Batman and Robin and Batgirl went to Londinium. Strange that was. In season two they had mentioned England. Why not just have the Terrific Trio go to London? (All that near trouble just to make a fictional city modeled after London!)
