Animated feature taking place during the last ice age, twenty thousand years ago: An unlikely trio made up of a wooly mammoth (voiced by Ray Romano), a sabertooth tiger (voiced by Denis Leary), and a sloth (voiced by John Leguizamo) take on the task of returning a human infant to his family. An acorn-crazy squirrel crosses their path from time to time, and along the way they discover what being a family is really all about. [1:25]

SEX/NUDITY 1 - Two female sloths and one male sloth flirt while in a hot mud tub.

VIOLENCE/GORE 3 - Sabertooth tigers attack a human camp and the humans chase them with spears; there's snarling and crunching. One of the tigers chases a woman and her baby and she jumps off a cliff into raging rapids; we see the mother pushing the baby out of the water onto a rock and then the mother disappears (she presumably slips back into the water and drowns). A group of humans with spears charge at an animal. An animal jumps and dangles from a cliff and another animal grabs him and tosses him to safety. A group of animals surround another animal threatening it, they jump and bite the animal and one is tossed against a wall and is apparently stabbed by a falling icicle. An animal is attacked by another animal and presumably dies from its injuries. A group of animals are knocked down by an animal that hits them with a log, and an animal jumps at another animal and gets stuck in a hole. A group of animals chase another animal that skis down a hill crashing into things. Two animals charge an animal, and two animals ram another animal that shoves them aside, scoops them up in his tusks and tosses them through the air. A flock of dodo birds do taekwondo moves (kicking and punching) to defend their collection of melons; a dodo falls into a smoldering pit, a sloth charges through a group of dodos knocking them down, and the dodos end up falling off a cliff. An avalanche starts, some animals are trapped in a cave and several icicles dangle precariously over their heads. Three animals and a human baby slide down winding ice-covered caverns and slam through a wall of snow and ice. Cave paintings become animated and show two animals being attacked by humans with spears; it is suggested that the animals were killed. An animal searches for a place to store his acorn throughout the movie and ends up in trouble with each try: once he starts the collapse of a glacier which sends shards of ice at him, he is squeezed between two glaciers, he falls over a cliff, he bounces off a rock wall, and he is stepped on by many large animals that are passing by (eventually he is gets stuck to the bottom of one animal's foot as if he's gum); he is also hit by lightning and is charred, and he also becomes frozen into a block of ice. An animal tries to climb a shear rock wall with a human baby in his arm; he drops the baby (who is caught before hitting the ground) and slips down, bonking his head a few times. A group of animals plan an attack on a human camp and talk about having a baby for breakfast, and a group of animals plan an attack on another animal and talk about "taking it apart." An animal jumps off a cliff, two animals fall over a ledge, an animal pokes himself in the eye with a stick, an animal is pelted with hail, an animal is hit in the face with a stick, an animal threatens another animal several times, and a baby pulls some hair out of an animal's trunk. Also, an animal steps in a pile of feces and when he shakes his foot to get it off it splatters on another animal's face, an animal takes a baby's diaper off, pretends it is dirty and tosses into the face of another animal, an animal takes shelter under another animal's tail, an animal is shot in the air by a geyser, a baby dangles from another animal's eyelid, an animal gets rolled up in a huge snowball, an animal's tongue gets stuck to some ice, and an animal's tail catches on fire. We see several sharp-toothed sea creatures frozen in ice. Some young animals play a game called "extinction" and they pretend to be trapped in a puddle of what looks like mud.
