When Sid accidentally destroys Manny heirloom Christmas rock and ends up on Santa's naughty list, he leads a hilarious quest to the North Pole to make things right and ends up making things much worse. Now it's up to Manny and his prehistoric posse to band together and save Christmas for the entire world!This was really good short movie, there were very nice plot, which was very well writtenThey also had some very funny moment in this movie, which Jokes that to do work for both Adults and kids will laugh, The animation was very well made and creative and very fun to watch with the whole family

I enjoyed the first two movies, was mixed on the third and liked Scrat's Continental Crack-Up. I was anticipating Ice Age: A Mammoth Christmas, and found it did live up to expectations. While short, perhaps a little too short, it is festive and fun, with the animation as great as ever especially in the beautifully detailed backgrounds and the music jaunty and putting you in the mood for the festive season. The writing even with the odd forced moment is mostly witty and funny(with Diego having the best lines), and the story is engaging and heart-warming with a warm atmosphere. I have always liked the characters and they are still entertaining, with Scrat stealing every scene he's in and Peaches is adorable, and the voice acting is solid across the board.All in all, a lot of fun and perfect for the Christmas season. 8/10 Bethany Cox

I'm basically older than rust - and my idea of holiday 'specials' is limited to the classics: 'Rudolph', 'Charlie Brown'... those modern cartoons that came out in the 80's were beyond lame, so I was somewhat suspicious of this when I first came across it.Now that I've watched it twice (and will probably watch it again soon), I have to say, WELL DONE!! Modern, familiar characters - portrayed in true-to-character form - and presented in a short, family friendly format. HOORAY!! Family entertainment, happy ending - and lots of laughs for adults too!So, added to my once yearly viewing with the aforementioned will be Scrat in his eternal hunt for the ultimate acorn.... and all the other 'Ice Age' alumni!

wow..came up with a new idea about Christmas. Flying deer,Santa on north poll..it is all like a dream story. it dragged me into my childhood. movie is just half an hour long. but all the characters are nice and cute. Specially "Peaches", she is cute,daring and spicy like her mother. In the Trailer of Ice Age 4,there is a new idea of "Continental Drift". The same is here. A short movie like this is very enjoyable. i recommend everyone to see this "short" movie, specially when you are in stress.The end of the movie is just awesome. Overall its a nice movie. And "Welcome Peaches...to the Ice Age"
