In honor of Halloween, here's what some of my trolls would do for it! Cut cuz it's a little long and I don't wanna clog y'all's dashes.
Ralkoa: She loooooves Troll Halloween! She decorates her hive, dresses more extravagantly than usual, and really gets in the scary-time mood. She's not a huge candy person, but she'll take what she can get, and she's more likely to go party or vandalize stuff than trick-or-treat. As for costumes, she has a lot of variety! Heavy metal looks with extremely strong makeup is a go-to, but she also likes characters from horror films, and would absolutely dress as a "sexy murderer" or something.
Malich: Similar to Koa; big fan of the holiday, but not much of a trick-or-treater. Would def like to do photoshoots in costume, and his are always either the sexy version of something or extremely blingy. If people aren't gonna look at him, what's the point of dressing up? He and Koa once went as a duality of rock: heavy, grungy, and rough for her, and blingy, bright, and put-together for him.
Tyzlee: Ty isn't big on holidays, to be honest, and Troll Halloween might be their least favorite. They don't like to be surprised or thrown off, and jumpscares are the bane of their existence. Still, they like the aesthetics, and can be found adding a spiderweb skirt or bloody accessory to their ensemble. They won't admit it, but in the past, they tried to make costumes from scratch. It didn't work out. The most they'd do in terms of "celebrating" is watching a slow, scare-free psychological horror or mystery.
Klanie: She doesn't love scary things, but she loves how creative everyone is around Troll Halloween! She always helps her friends with costume ideas, and has even made costumes for them on occasion. In the end, she can never decide on one for herself, and takes whatever suggestion her friends come up with for her. She's definitely the one to stay hive and hand out candy to anyone who comes by, though probably not chat too much.
Akryla: Another Troll Halloween lover! Other than experimenting with her face paint, she doesn't usually dress up much, maybe putting on some accessories, but she loves doing little stunts to earn extra candy while trick-or-treating! Saal, of course, goes with her, and she does his paint as well. She might get daymares from the movies he'd want to watch though.
Wynnie and the Cheska twins spend Troll Halloween together! Wynnie and Galinn will put on a horror movie marathon, complete with snacks and decorations, and Silnor will force them to put some musical Halloween flicks into the list (he loves the Nightmare Before 12th Perigees). They may go out trick-or-treating, and if they do, Wynnie and Galinn will do matching costumes. They've been Leatherface and Chop-Top Sawyer for the last 2 sweeps. Silnor likes to look a bit more put-together and dapper (the Phantom of the Opera is his go-to), though he did go as Drayton for them one sweep to complete the trio.
