I love reading headcanons so I figured I’d make some of my own, I’m a stickler for detail so I hope y'all enjoy and you should expect a few more after this too 😉

PAPYRUS: The most adorable cutie patootie cinnamon roll ever, a major giggler mixed with loud ‘NYEH HEH HEH’S’ at every conceivable interval! He loves tickle fights especially because he gets to be a little kid in a way and he loves being able to retaliate and make other people laugh more than anything else.

His normal ticklers are Undyne because she loves any opportunity to beat him (and she thinks he’s adorable but she’d never say that), also Sans because he’s the big brother and Papyrus loves having fun with his brother, and sometimes Frisk because they love hearing Papyrus’ laugh and loves spending time with him too. Also, Mettaton takes a chance whenever he can because he simply cannot get enough of darling Papyrus’ laugh and multiple reactions, but Papyrus loves all of it nonetheless because he gets to connect with friends.

His worst spots are his ribs which are always certain to get the giggles bubbling away, his spine is his real bad spot though and never fails to elicit squeals and the odd snort, which everyone else never fails to tease him about. In short he is the adorable lee of the underground 😊

SANS: This guy pretends to be the hard guy, being all suave with his puns and cheeky mischievous nature, however when it comes to tickling he becomes genuine putty in his ler’s hands (literally in their hands 😂). His loud belly laughs and yelps let Sans finally let go of his worries and just laugh freely.

Not many people know of this little weakness but there are a select few, Papyrus for one since he knows practically everything about his brother, and he loves the opportunity to turn the tables on Sans and relishes in the power that most little brothers only dream of; however Papyrus is discreet since Sans never can hide his embarrassment. Toriel knows too, she and Sans are undoubtedly close and she relishes in making him laugh with something other than puns, I’m pretty sure she gets some enjoyment from embarrassing him too! Frisk is the only other person who knows and isn’t the sort of person to take advantage, but if they ever see that Sans is sadder than usual they’ll give him a little cheer up. Which Sans always appreciates.

His bad spots are his ribs which unlock his deep chuckles which quickly morph into strong belly laughs when you reach his ghost-tummy. Light skitterings are all it takes to make him a mess, however when you do relent you better start running because he’ll give you a hell of a bad time in revenge. He’s the revenge taker of the underground 😊

TORIEL: Just need to say first….GOAT MOM IS BEST MOM! Okay, so Toriel is the definition of adorable when it comes to tickles; squirming, giggling and curling up into a cute floof ball make her an immediate target. I mean who could resist that cuteness?!

Literally everyone knows of how sensitive Toriel is but few take advantage because they would always feel bad about taking advantage of her! However that doesn’t stop everyone. Sans is always the first to give her a few pokes if he feels her puns are getting more attention than his 😂 Also, when she gets sad about her past family life Sans will always be there to get her spirits back up, she always appreciates it even if she doesn’t immediately show it. Her only other proper tickler was Asgore, even though it was mainly in the past he always tickled her because he loved seeing her laugh and be happy. Honestly like how a couple really should be, always with care and attention.

Her main tickle spots are her floofy, furry tum tum which gets her giggling and squirming but her death spots are behind her ears and the bases of her horns and i CAn’t eVEN BECAUSE SHE SQUEALS AND BLUSHES SO MUCH IT’S UNBELIEVABLE! In short, Toriel is the most embarrassed ticklee of the underground.

UNDYNE: Whoo boy you have to be one frickin determined cookie to be able to unlock the ticklishness of this fearsome warrior, she’ll deny it everytime but she has her sensitive spots just like everyone else. Her loud boisterous laughter is hilarious to behold 😂

People know about Undyne being ticklish but are always far too intimidated to even try for fear of her strength and her capacity for revenge. There are a few who do though 😉 Tickling Undyne is one of Alphys’ favourite things to do because she’s the only one who ever gets to see her all giggly! They always have tickle fights together and Alphys enjoys getting a little payback now and then because who doesn’t love tickling their bae? Papyrus has tickled her once (by accident in training) but she swore him to ultimate secrecy, with a little persuasion containing a ticklish theme of course 😉

Undyne’s main tickle spots reside at her ear fins where the skin is EXTREMELY sensitive, like legit she will break a freakin window with her screeching holy fuck. Her gills are also pretty sensitive and will make her scrunch up her neck and giggle like a kid it’s so cute! But her death spot is definately her feet and particularly the webbing and this is probably the only thing that would get her begging for mercy….before she abruptly kicks you in the face 😂 Undyne is the most resistant lee of the Underground.

ALPHYS: I can’t even with this smol weeaboo child like talk about a major SQUEEEEEEEEEEE at the very thought of her being tickled holy hell! She gets ever so embarrassed and takes about an hour to recover, like she will legit still be engulfed by a giggle fit for ages! I think she kinda enjoys it too because she likes it when her friends make her laugh and cheer her up when she’s having a bad day.

LITERALLY EVERYONE TICKLES ALPHYS! I swear at one point everyone banded together and agreed to make it a group activity or something 😂 Undyne loves to tickle her because she loves her laugh, Mettaton tickles her because he’s a mischievous little shit and loves making her squirmy and embarrassed. She may not be as close with everyone else but they will always team up and tickle the living daylights out of her in case she’s been working too hard or feeling down. Because every single goddamn being loves her to pieces because it is literally impossible not to 😊

Alphys is a walking tickle spot like poke her anywhere and she’ll jump a mile! Although I have to say that going for her tail will elicit uncontrollable squealing, giggling, blushing and squirming all in the space of a microsecond, like every aspect of her is a bundle or nerves! Seriously if you so much as poke her tail….holy shit she will squeal so hard and her giggles will give you a cuteness induced heart attack, like she literally cannot deal with it! Alphys is the most adorable lee of the Underground.

METTATON: This sexy, fabulous superstar will have you thinking his confidence means he couldn’t possibly be ticklish. Oh darling do I have a surprise for you! It varies between his forms, boxy and NEO aren’t as ticklish and you’d probably only get a few giggles. His EX form however….darlings you are certainly in for a treat 😉

Alphys constantly takes advantage of all his little nerve receptors (that she herself installed might I add) are I swear she gets a kick out of making him squeal! Another few people who like to take advantage include our lil Blooky who enjoys phasing through his cousin’s metal body to send shockwaves and shivers to get him giggling! However our star’s main predator is Papyrus who simply relishes every noise and reaction he can get from his mischievous robot, not that Mettaton really complains about it of course 😂 I personally think Mettaton rather enjoys being made to giggle and laugh, especially with all the teasing people can dish out on him!

When it comes to specific spots the main ones to go for would definately be his black waist, hips and thighs which aren’t made of hard metal, but just a softer material. This makes them perfect for squeezing which will have him bucking and snorting in no time! Also, it wouldn’t do any harm to skitter around his pink soul a little, you’d get the most delicious squeaks and giggles! 😂 Even though he’ll get his revenge on you after, he’ll never really try to stop you and go quiet if you ask him about it….. you can all make of that what you will 😂 Mettaton is the bashful lee of the Underground.

FRISK: AHHHHHHH SMOL INNOCENT CHILD TOO PRECIOUS FOR THIS WORLD!!! Ahem…this adorable ass human’s laughter puts a smile on everyone’s face so tickling Frisk is basically everyone’s favourite hobby. Frisk’s giggles are basically drug-like and people cannot get enought of them, however that puts our lil human in a bit of a situation now and again *cough* all the frickin time *cough*.

This is rather similar to Alphys since EVERYONE TICKLES FRISK!!! Bless this child honestly it must be a curse being that adorable. Papyrus will do it because he loves the scrunchy expressions they make, Sans does it because he’s a cheeky shit and loves making the kid laugh more than anyone else, Mettaton is also a cheeky shit and is always fascinated with the way humans *coughhh* Frisk *splutter* react to everything 😂 Undyne is relentless and insists it’s a type of training to tougher Frisk up (I call BULLSHIT FISH WAIFU), Toriel is motherly and loves seeing Frisk laugh freely, and pretty much the same with Asgore on that front too 😊 Frisk literally generates happiness so no wonder everyone wants to hear that adorable hooman laugh and giggle all day!

Frisk may not be a complete walking tickle spot but that doesn’t mean they’re safe, oh hell no honey! If you so much as brush their neck, shoulder or ribs then they are fucking GONE! Childish squeals and giggles and unrelenting squirming will occur without fail! Their worst spot however….if you so much as think about going for their knees then their determination will go into goddamn override. There must be a hella big buch of nerve endings residing there because even after someone’s relented the twitching and giggling will remain for about half an hour 😂 Arggghhh I am getting nausea from all this fluffy goodness christ help me. Frisk is happiest lee of the Underground.

ASGORE: Oh this adorable goat dad he is just so perfect 👌 Deep chuckles, belly laughs and snorts are your rewards when you get at his majesty and you certainly will not regret it….actually thinking on that you might do, especially if he himself is in a mischievous mood!

Very few people actually know of our King’s little weakness because no-one has ever really gotten close enough to him to find out let alone try, but there are a few exceptions of course 😂 Namely Toriel, I mean c'mon couple tickle fights are inevitable aren’t they! They still do at present since they’re still close friends, that sort of connection doesn’t really go away. Another would be Undyne, she found out in a training session and loves trying to embarrass him with it, she relishes in getting rid of his big, tough kingly act and gets him to loosen up; he’s always grateful for that. Frisk also knows cuz the smol child is always DETERMINED to make everyone happy and they love his deep, chuckly laugh!

His worst spots would certainly be around the base of his horns and around his ears, but make sure you’re careful cuz if you let his head thrash too much he’ll pull a damn muscle! But his kill spot is his floofy tummy! Go to town there while you can because the guffaws, loud laughter and eventual BLEETS won’t last long if he overpowers you. Then yousa better be ready for teasy papa ler! In short though, he’s the hidden lee of the underground.

ASRIEL: SMOL GOAT CHILD WHO NEEDS ALL THE PROTECTION IN THE WORLD TOO CUTE AND HUGGABLE…ahem, well to business. This lil giggly ball of floof will give you endless joy since he’s ticklish EVERYWHERE!!!

His main ticklers are his parents because they’re mainly making up for lost time, and because they love hearing their son’s laugh because who wouldn’t cherish something so pure?! Since Frisk is his hooman bestie they never hesitate to get him if they even sense a frown or drop in his mood, what kind of friend would they be if they didn’t get him giggling and squirming? His last main ler may surprise you, it is in fact sans. Asriel (when he was saved and brought to the surface DON’T QUESTION IT JUST ROLL WITH IT PEOPLE) was always trying too hard, sans forgave him ages ago because he knew he had no real control, and one day he saw Frisk reduce him to a giggled out ball o’ floof. So of course, being the mischievous shit he is, decided to cheer up the kid. It was something they both needed, then Asriel got the message and is a lot better for it (wow rambling soz).

His tickle spots are DEM EARS, DAT TUM, AND DEM HANDS AND FOOTS. He’s so damn giggly and his voice goes up like 3 octaves and then the BLEATING gosh darn, once he starts he can’t stop. He’s especially sensitive to the lightest touches, his feet are by far the worst, particularly the toe pads; his laughter literally goes silent. He’s always way too exhausted and is too kind to ever get anyone back, all in all he’s the lee that needs it the most.
