 Mighty Mouse has his familiar moniker for the first time in this  cartoon. He was Super Mouse for his first seven cartoons (although  any reference to that name is edited out of the TV versions).  Terry, Paul (I) (qv) changed the characters name so he wouldnt  be confused with another "Super Mouse" in a comic book (not, as some  believe, because Supermans copyright owners threatened to sue Terry  for infringement).
