Directed by Mike Thurmeier & Galen T. Chu. [1:34]

SEX/NUDITY 2 - Two sloths kiss. A female mammoth throws kisses to her fiancé. A sloth kisses another sloth on the cheek. A male mammoth hugs another male mammoth (son-in-law and father-in-law).
► A sloth practices proposing to another sloth (please see the Violence/Gore category for more details). A rabbit and a sloth flirt in a hot tub. A dinosaur licks a weasel on the face as a thank you and a baby dinosaur breaks its shell to kiss the weasel on the cheek. An animal carries another animal through a crystalline cave and they seem to be romantically involved (they flirt).
► A flying dinosaur remarks about the cold and says, "Parts are retreating into other parts." A rabbit comments about dating a "cougar" (an older animal). An animal talks about playing "naked bingo."
► We see a sloth with the fur burned off his belly and we see his nipples glowing. A male animal dresses like a woman and sways his hips. A squirrel beams himself across a platform and we see him reform (once with nuts as nipples, and once he is shown without any fur and he holds his paws over his crotch). Two male animals model garter belts and pose seductively. An animal is seen with a leaf over his crotch.

VIOLENCE/GORE 3 - A squirrel with an acorn pokes out through a snow drift, then slams the nut on the ground opening a hole that he and the nut fall through (the nut hits the squirrel on the head); the squirrel slams the nut into ice and it reverberates and shakes him, then he slams it into another patch of snow that uncovers a space vessel that he starts and it crashes through the ice and shoots into space and we see the G-force press the squirrel flat into the seat and the vessel bounces off planets like a pool ball. A squirrel in a space vessel is slammed against a glass panel, through around the cabin and shot out into space where he dangles from a tether; he dodges meteors, cashes through a large one and buries his acorn in it, breaking the rock apart and he is left floating in a space helmet. A squirrel beams a nut and then himself across platform and we see him reform in different shapes and with the nut in different places (as his head, as nipples, and once he is shown without any fur and he holds his paws over his crotch). Several birds are shot out of the sky and we see them falling in flames.
► An elderly animal is struck by lightning and falls to the ground; she is OK. Electricity blasts into the air and hits three flying dinosaurs (they glow and we see their skeletons); they are OK. An animal jumps on the tail of a flying dinosaur and the dino panics until another dino swallows the animal; we see the animal poking the dino's stomach and then it reacts as if it going to pass it out the rectum before he spits the animal out. Flying dinosaurs steal another dinosaur's egg and fly away and a weasel breaks a large rock that's pieces trap three flying dinosaurs (they are OK). Flying dinosaurs try to grab a weasel; he jumps off the tail of one and bounds into brush. A weasel goes into a forest that is exploding to rescue a baby; he is thrown into the air and lands holding a pumpkin wrapped in a leaf. An animal trips and a stick is jammed up its nose (he's OK). A sloth rubs his eyes with a poison ivy leaf and we see the eyes turn red and swell shut along with his nose turning red. A squirrel in a space vessel adjusts the gravity and is crushed under his own weight; we see his skin fall off leaving a skeleton and he is rolled over by an acorn (we hear squishing sounds and he moans).
► The air becomes electrified and animals are shocked and their hair stands on end. Meteorites crash to the ground and animals run and hide underground; a tree topples and nearly crushes a mammoth, two animals are thrown through the air by an explosion, a flaming rock bounds over several animals and they hide in a cave and an explosion blasts the fur off one character and when he turns around we see him without fur and his nipples are glowing. Several scenes show a giant asteroid speeding toward Earth. Fragments of meteorites are attracted to each other and pin animals between them, and then cover them completely (the animals are OK).
► A weasel crashes into a rock and falls through a hole before landing in a cave where he finds an obelisk. A weasel jumps through the air and bounces off rock walls while teasing flying dinosaurs and retrieving an egg that they stole. A flying vessel crashes into Mars and we see it change from an Earth-like planet to a barren, red rock and we see a creature that had been on the planet turn to dust. An animal is pinched between quickly closing doors repeatedly and his shape changes briefly.
► Two animals fight with punching, shoving, kicking, and one pulls the lip of the other, and one hits the other with a stick. A sloth breaks up with another sloth and stomps away complaining that he is "too clingy" as the male sloth wraps his arms around her neck. A sloth talks about having his and his intended's burial plots and we see an animal standing in a hole and next to another (presumably having dug the two graves). A sloth says, "I wish it had a face so I could smack it." A weasel sings lyrics, "Daddy's gonna blind this remaining eye." A sloth threatens a Llama.
► Animals cry like babies, an animal sets something on fire and a spark of a fire sets another animal's tail on fire as a test to see if another animal would know what to do in a stressful situation with no help. A mammoth throws snow in the face of another mammoth (playfully). Two animals faint in a couple of scenes. An animal faints on a couple of scenes. An animal fills its mouth with grapes and then spits them at another animal in rapid fire (no one is harmed). A mammoth knocks a rock into the head of another mammoth knocking him out and he falls through ice into frigid water (he's OK).
► Two saber toothed tigers eat a red fruit that leaves streaks of red on their mouths and when two young animals see them, they ask, "Are you going to eat us?" Two animals turn their tails toward the audience, lift their tails and make a remark about another character stinking. We hear an animal screaming, then see her being massaged by another animal. A Llama screams in frustration.
► An animal nearly licks a pile of feces. A weasel wears an eye patch made from a leaf and behaves like a pirate. A sloth scratches his buttock and then smells his fingers. A Llama spits several times and we see the goo splatter. A sloth asks for help and says, "My face is dangerously close to my butt."
