Undertale special interest kicking in... I swear I'm never getting tired of these guys...
I can imagine them sometimes meeting up Post-Pacifist for game nights. Like... board games, card games, video games... I have a few headcanons about it.
Card/Board games:
Let's address the elephant in the room: Monopoly is banned. Just straight up banned. They played once... Never again. Let's just say by the end of the night there were magic spears wedged deeply into Toriel's new wallpaper... and the wall... and the brick of the house... And the window was shattered. Yeah, Monopoly, it's banned, it's banned.
Papyrus has no poker face whatsoever. Meanwhile, Sans and Frisk have VERY impressive poker faces, and they're both aware of it. Once, they formed some sort of secret alliance and they dominated poker night. It was Frisk's first time playing, too!
I imagine Frisk would just be a natural at all games, hands down. Well, kind of. They don't always win, but they learn very quickly. Jack of all trades, I suppose.
Undyne has this habit of flipping boards (a classic) and shooting magic spears whenever she loses at a game or just gets EXTREMELY passionate about it. Although, if Alphys or Papyrus are the ones that beat her, she'll grit her teeth and act happy for them, just to make them happy.
Unfortunately, Papyrus picked up on Undyne's bad habit and bones started scattering the walls. Toriel had to ban magic bullets in the house after one of them almost gave Frisk a concussion.
Asgore is pretty good at card games, actually! I like to imagine he sometimes spends time with old friends of his, like Gerson and stuff, and they would have tea and play games while they chat, so he's had a lot of practice.
Toriel, on the other hand, hasn't played any board games or cards in AGES thanks to her isolation in the Ruins. She's not terrible, but she's not particularly GOOD at them either.
Sometimes, certain members of the group would try to break Sans' calmness, because while everyone had gotten annoyed at one point or another during game nights, Sans never did. Long story short, nope, he's just too chill. He's just happy to be here.
Once, Alphys bought a Mew Mew Kissy Cutie board game for game night, and she was so excited to show everyone the ropes (and dominate the night for once). She only won one game. And then she had an identity crisis afterwards!
Snacks! They do a rotation on who gets to be in charge of the food! Undyne and Papyrus are NO LONGER in this rotation after they brought in flaming spaghetti and almost set the couch on fire. Even then, you could only really trust Frisk, Toriel and Asgore with the snacks, since Alphys doesn't cook (she brings in store-bought cupcakes, it's the thought that counts), and Sans always forgets or is just too lazy to get snacks, so he orders pizza.
Video games:
They meet up to play stuff like Smash Bros, Mario Kart and Mario Party, but when they play online multiplayer games, like Minecraft, Terraria etc. they just stay home and go on a Zoom call or something. It's a lot less stressful for the introverts of the group (mainly Alphys, but I suppose Toriel could qualify [Undyne and Papyrus are absolutely extroverts; Sans and Frisk are moreso ambiverts, I think]) because they don't have to go out to do it! Yay!
They do all the things typical friends do when they're playing online games! They troll, they tease, they laugh, they help each other out, they TRY to work as a team (emphasis on TRY)...
One of the games I'd like to see them play is Human Fall Flat (I have that game and I play it with my sister :]). I want to see some RAGE. I'm sure Papyrus would love doing the puzzles, but at the same time, I'm sure the others not cooperating or knowing what's going on would tick him off. Yessss... Let Papyrus rage.
Sometimes Alphys and/or Sans would trail off into some scientific conversation or tangent, and after a minute or so, the others would start yelling over them, "NERD!!! NERDS! NERRDDD!!!" Alphys would get flustered, and Sans would desperately try to keep his composure and try not to burst out laughing.
Undyne and Papyrus have the extraordinary ability to make even the calmest, simplest games intense. ESPECIALLY Undyne, oh my goooood. Though I guess she could use the extra stimulation, she will NOT settle for a game with a slow pace. So much for Animal Crossing.
In addition, the gang can get VERY competitive at Mario Kart and stuff. Undyne is obviously the most competitive, but I think Papyrus and Alphys would want to try and impress her. Frisk and Sans? Nah, they're chilling. They don't care, they're just here to watch the chaos. Yeah... There's a reason why Asgore and Toriel don't often play games with these guys. Though they would watch and look upon them fondly. I dunno, it just seems cute.
