Ohhh, Christmas-themed 'Undertale' AUs are such a cozy rabbit hole! One of my favorites is 'Snowdin Holiday Hijinks,' where Sans tries (and fails) to organize a secret Santa for the skeleton brothers, leading to Papyrus accidentally gifting everyone spaghetti ornaments. The writing nails the humor and warmth of the original game, plus there’s a sweet subplot where Frisk convinces Toriel to host the party at the ruins.
Another gem is 'Mistletoe Misadventures,' a Chara-centric fic where they’re resurrected as a ghost and haunt the party, playing pranks until Flowey—of all people—helps them reconnect with Asriel through old holiday traditions. The emotional payoff had me tearing up while laughing at the chaos. Bonus points for the author including a recipe for 'Butterscotch-Cinnamon Pie' in the notes!

Ever since I stumbled upon the Undertale fandom, I've been obsessed with the idea of blending AUs with holiday cheer. Hosting an in-game Christmas party in an AU setting? Brilliant! First, pick your AU—'Underfell' for edgy decor, 'Underfresh' for meme-y vibes, or 'Dusttrust' if you want melancholy snowflakes. Modify sprite sheets or use dialogue patches to Christmas-ify characters: Sans in a Santa hat, Papyrus with tinsel-scarf upgrades.
Next, map out party 'locations'—Snowdin’s town square for gift exchanges, Grillby’s with eggnog-themed menus (healing items renamed 'Mistletoe Cider'). Use RPG Maker or UndertaleModTool to add festive battle encounters (imagine fighting 'Krampus Flowey'). Share the mod files with friends or stream the party live, complete with AU lore trivia games. Bonus points for composing a chiptune remix of 'Carol of the Bells' with Temmie vocals.

Man, Undertale AUs and fanart are like a rabbit hole I love tumbling down! If you're hunting for Christmas party stuff, Tumblr's a goldmine—tons of artists post seasonal AU content there, especially around December. Try tags like 'undertale christmas AU' or 'undertale holiday fanart.'
DeviantArt’s another solid spot; some artists even create whole comic strips of AUs celebrating winter festivities. Oh, and don’t sleep on Twitter/X—searching '#undertaleAU' with festive keywords often surfaces hidden gems. Pinterest can be surprisingly good too, though you’ll need to sift through reposts. Honestly, half the fun is stumbling onto some artist’s cozy interpretation of Sans in a Santa hat while Papyrus decorates a skeleton-shaped tree.

Undertale AUs have this wild, creative energy that makes imagining a Christmas party totally chaotic in the best way. Picture 'Underfell' Sans showing up with a smirk, bringing 'gifts' that are just rocks wrapped in barbed wire—classic edgy vibes. Then there's 'Swap' Papyrus, cheerfully decorating the tree with spaghetti tinsel while 'Horror' Sans lurks in the corner, nibbling on bone-shaped cookies. 'Dust' might crash the party late, trailing glitter and existential dread, and 'Ink' would splash paint everywhere 'for festive colors.'
And oh, 'Error' would absolutely 'accidentally' glitch the mistletoe into a black hole. The real MVP? 'Fresh' Sans, rolling up in neon shades and a Santa hat, handing out cursed memes as presents. It’s less a holiday gathering and more a multiverse dumpster fire—adorably so.

the Christmas party events are always a highlight! From what I've gathered from fan communities and creators, these events usually kick off around mid-December, often between the 15th and 20th. Different AU groups might stagger their dates, but the big collaborative stuff tends to cluster around that time.
What's cool is how each AU puts its own spin on it—'Underfell' might do a gritty 'Naughty List' theme, while 'Underswap' goes full-on wholesome gift exchange. The fanart and comics that flood Tumblr and Twitter during this period are pure serotonin. Last year, I stayed up way too late scrolling through #UTChristmasParty tags.
