Mighty Mouse saved the day many a time, so doubtlessly he has saved the day in many other times, too, but so far I’ve seen only one such episode (“Prehistoric Perils,” 1952) in which our mouse goes in our villain’s machine back to the dinosaurs to save Pearl Pureheart.
And now, my little papoose, I shall take you off in my time machine.
