- Ignore it. Anatomy? What anatomy? For the purposes of the work, a duck's bill can become just as pliant and squishy as human lips so that Donald and Daisy can have their smooch. Funny Animals, or just those in less-realistic works, tend to get saddled with this option.
- Come up with an alternate gesture with the same meaning. After all, real-world animals do have ways to express affection, so why not? Common choices for this one include: licking (like dogs), rubbing noses/snouts, bumping foreheads, or crossing necks (which can also substitute for a hug). Works with Talking Animals, or more realism, tend to use this. Alternatively, it might just be more whimsical.
Examples of Type 1:

Films — Animation
- In The Swan Princess, Lt. Puffin manages to give a kiss to the back of Odette's hand. The tip of his beak kind of... folds back.
- Chicken Run makes heavy use of the Almost Kiss because the animators weren't sure how to animate chickens kissing. The kiss at the end is staged so that the beaks are hidden from view.
- Rio has its two main birds kiss despite the movie having a surprising amount biological correctness up to that point. Somewhat justified: parrots in Real Life do bite each others' beaks affectionately, which is not that different from a human kiss.
- Lady and the Tramp has the famous Spaghetti Kiss where they end up accidentally smooching. Also, even more anatomically improbably, the Siamese cats use their tails to "shake hands" with each other.
- Lions in The Lion King usually kiss by licking each others cheeks however they seem to have a concept of human kissing. In The Lion King II: Simba's Pride Kovu and Kiara accidentally kiss and get embarrassed afterwards, though it could be argued they were embarrassed about the physical contact instead of the action.
- My Little Pony: Friendship Is Magic has actually shown both variants of the trope. Spike fantasizes about kissing Rarity in "A Dog and Pony Show" and is kissed on the cheek twice by Rarity in "Secret of My Excess". Also, at the end of "Canterlot Wedding", Cadence and Shining Armor are shown kissing in the usual way.
- Two pigeons that show up in the Futurama movie, The Beast With a Billion Backs French kiss. Interestingly, the two pigeons are otherwise normal pigeons and their beaks don't get as pliant and squishy as human lips.
- The kissing gourami is a species of fish that has large lips and actually kisses like a human would. Inverted in that those kisses are a form of fighting.
Examples of Type 2:
Anime and Manga
Films — Animation
- The Lion King:
- In WALL•E, a robotic "kiss" is more like a static electrical shock.
- In the Animaniacs movie, Wakko's Wish, Yakko rubs noses with Dot. As above, it's a sign of familial affection.
- The horses in Spirit: Stallion of the Cimarron mostly use nuzzling or neck-crossing. Spirit also gives Little Creek a "hug" by putting his head over Little Creek's shoulder near the end; real-life horses actually do this.
- Belle and the Beast in Disney's Beauty and the Beast never kiss, but the Beast frequently runs his hand through Belle's hair. He also does this as a human prince before he and Belle have their first kiss, which seems to reassure an understandably floored Belle that he is the Beast.
- In Balto, Jenna and Balto nuzzle each other or touch noses to show affection.
- The Land Before Time: Both the original movie and the thirteen sequels has affection in the form of neck-crossing, snout-nuzzling, and the occasional platonic lick on the cheek. This can lead to a little confusion, as baby dinosaurs who are quadrupedal often use their snouts as hands in games like tag. One circumstance had Littlefoot briefly reacting to an unexpected "tag, you're it" from Ali as one might to an a Accidental Kiss.
- The Aristocats shows Duchess and O'Malley sharing an affectionate moment by holding tails as though they were holding hands.
Films — Live-Action
- In Godzilla (2014), the MUTO couple nuzzle each other and touch noses, making beeping noises as their eyes flash towards each other.
- In Warrior Cats the cats often rub their faces together or wash each other as a sign of affection ("sharing tongues" as its called). Cats also touch their noses to different parts of their bodies to signify different gestures, such as to comfort another cat or to show respect. Cats will occasionally hook their tails together however this is never platonic, though sharing tongues does take place between friends or family.
- Dinoverse: Bertram and Canadayce, in the bodies of short-beaked dinosaurs, spontaneously try a kind of beak-locking gesture from which Canadayce can tell that Bertram's eaten peppermint. Although Bertram had a crush on Canadayce he didn't feel anything from the kiss - dinosaurs, not surprising - and it's not until they're human again and she can kiss with lips that he's actually affected. In other books with beakless dinosaurs there is face-nuzzling. A dinosaur does this a lot with a girl in a dinosaur's body; when the dinosaur ends up Sharing a Body with another kid, this happens.
He leaned in close and brushed his lips with hers. The part of him that had once been an Acrocanthosaurus didn't understand this odd custom.But it felt certain it could grow to like it.
- For the dragons of the Age of Fire verse, a crossing necks is the equivalent of a kiss, while folding wings over another is a hug.
- The Kantri of Tales of Kolmar have rigid faceplates, but have affectionate gestures similar to the above dragons, as well as twining together and touching faceplates.
- Raptor Red has the titular raptor and her fellow raptor kin performing things such as neck presses, muzzle bumps, grooming, and leaning into each other as gestures of affection. This is meant to evoke comparisons with present-day birds, due to similar physiology and equally similar limitations of that same physiology (most notably, a lack of lips or mouth motions beyond open and close).
- The musical version The Lion King follows the movie's model by having the lion's hug and nuzzle, despite them being played by human actors able to kiss now.
- Nuzzling noses is apparently a common display of affection among the monsters in Undertale, to the point where they even made a competitive event out of it. A Battle Couple you encounter were the runners-up one year. Asgore and Toriel were the multi-year, undisputed winners until their divorce. With them out of the way, Dogamy and Dogaressa finally took the title.
- According to Word of God, Gargoyles stroke hair, horns and brow ridges rather than kiss. This can be seen between Goliath and Demona in the 5-part series premiere, "Awakening."
- Angela and Broadway's kiss was explained as Angela being raised by humans and Broadway having seen a lot of movies. (Admittedly, that doesn't explain the flashback of Demona kissing the petrified Goliath goodbye before leaving Castle Wyvern in the City Of Stone arc.
- Elisa and Goliath share a very human kiss at the end of season 2. Well, it was more like she kissed him and he was too surprised to really respond ... but that didn't stop him from having a very goofy grin on his face after.
- Elisa and Goliath kiss again in issue 7 of the Slave Labor Graphics comic book. This time she strokes his hair first, then he picks up and kisses her.
- My Little Pony:
- In the original My Little Pony TV Specials ponies used to nuzzle and lick each other like real ponies do. Further in G1 the characters became more anthropomorphic and the licking was phased out. It hasn't been used since G1, though ponies have been shown nuzzling in works such as My Little Pony 'n Friends.
- In the My Little Pony: Friendship Is Magic episode "Hearts and Hooves Day", pony couples are shown performing Eskimo kisses. This appears again in "Hard to Say Anything" when Big Mcintosh nuzzles Sugar Belle's nose.
- The Penguins of Madagascar:
"Mmm... Peck peck. Pecky, love peck... (I'm trying to kiss but I got no lips)... Peck... No, wait! I'm getting good at this pecking."
- Lampshaded in the episode "The Falcon and the Snow Job." After rescuing Kitka (the Girl of the Week falcon), Skipper goes in for the big kiss, only to be interrupted by King Julien mocking them (and making pecking gestures with his hands):
- Though a frame by frame shows that the animators know how to animate CGI penguin kisses by when Private kisses the Peanut Butter Winky in "Skorca."
Hans: You should know I kissed your sister. On the lips!Skipper: I don't have a sister. And if I did, she wouldn't have lips.Hans: Then who did I kiss?
- Hans the Puffin in Huffin' and Puffin:
- Jimmy Two-Shoes: Cerbee and Jasmine kiss by licking.
- In episode XCIV of Samurai Jack a few of the assasins from the Cult of Aku see a buck and doe nuzzling their noses together. Being raised as Tyke Bombs, they don't understand what such affectionate gestures mean.
- Dog owners often refer to their dog licking a face as getting "kissed", more so for small breeds. Puppies lick their mother's muzzle to get her to vomit food for them. In adulthood, the same gesture demonstrates acceptance of the lick-ee's higher rank.
- Cats nuzzling their owners is also often said to be this. They also headbutt as a sign of affection. The page image shows Nala doing this to Simba (she's also rubbing her muzzle on him, but it starts as more of a headbutt).
- Cats have scent glands in their faces, and they rub things to declare to other cats "this object belongs to the cat that it smells like." So a cat rubbing its head on you is saying it likes you .... well enough to claim ownership of you. Cats also slow blink as their form of an air kiss.
- Among sociable mammals, such as chimps, baboons, or rats, mutual grooming can serve a similar function to human kissing. In fact, the male Crab-eating Macaque will groom the female so she'll agree to mate.
- Puffins 'kiss' using a process called 'billing'. They rub both their beaks against each other in a way that is similar to kissing. Awwwwww.
- Inverted by 'kissing fish'. What looks like a kiss is actually two males fighting for dominance and the right to breed with local females.
- Parrots will nip at each other's beaks to show affection, either between mates or close family members (siblings, children and parents, etc.). They'll do this with humans they like too, usually but not always gently enough not to hurt our "soft beaks".
- Mice will sometimes express affection or friendship by "holding tails", coiling their semi-prehensile tails together as they stand or lie side by side.
- Social whales and porpoises, having no appendages suitable for hugging, will rub or nudge one another to express affection. Dolphins do the same, and pairs will also swim in perfect synchrony with bonded companions.
