Mr. Peabody and Sherman were the stars of one of last winter’s most popular animated films. It was a well-deserved and long overdue promotion, since the characters got their start in 1959 as supporting characters in the Rocky and Bullwinkle cartoon universe. Well, the tables have turned. In the new 3-D Blu-ray of Mr. Peabody & Sherman, which arrives Oct. 14, the clever squirrel and not-so-clever moose return for another crazy adventure titled “Another Fine Moose You’ve Gotten Me Into,” or “The Man In The Iron Moose!”

Of course, if Rocky and Bullwinkle are back, then Boris Badenov and Natasha Fatale can’t be far behind. In this new five-minute short, written by Thomas Lennon and Robert Ben Garant and directed by Gary Trousdale (Beauty and the Beast), Bullwinkle has fallen head over heels in love and is getting married on a cruise ship. But Rocky isn’t so sure about Bullwinkle’s new squeeze: she’s kind of stiff, almost robotic, and, well, she can shoot fire out of her eyes.
