Well I have Headcanons for my OCS but since they're coming from me, are they technically canon? I have no clue...I'll let you guys decide. But for now, I'll just leave it off as a 50/50.
~~~
1. Despite not doing it often, Bdog loves to cosplay.

2. Bcat reserves atleast 3 hours a day for his cat naps.

3. Jed's favourite colour used to be red until he switched to orange since he knew too many that also liked the colour red.

4. Raine dislikes rainstorms.

5. The only reason why Baxter carries around a headset with a mic is so that he can grab everyone's attentions when something dramatic/romantic/fluffy happens in his Biden fanfiction.

6. Bdeani spends 2000$ a day on perfume, clothes, handbags and makeup.

7. Bcopper owns a helicopter that he uses to go to school.

8. Gabbie has been to every biome in the world aside from the dimensions like the end and the nether.

9. Wyatt learned how to keep his endurance stable due to the fact that he's always chasing bandits and searching for his missing sister around town.

10. It happens occasionally where Reagan swears out of the blue despite keeping her curses silent.

11. Elliot only learned how to bake because of his cousin(Lukas). His parents never bothered to teach him how to cook or bake.

12. Ethan will get very annoyed if you call him a Romesse child.
"Aw come on! Do I really look like those guys?! I thought I was creative with my look for once!"

13. Erika isn't sassy at all despite the hints of pink everywhere in her appearance.

14. Faith enjoys to sing when she's alone. She's too shy to sing in front of Ethan and Erika and even Fred himself. But there were a few citizens who caught her singing once and described her voice as "one of an angel."

15. Filly has an irrational fear of caterpillars.

16. Juvvy's record of trying to escape the sunshine institute was 13. Eventually ending up in a cell close to Xara's and attempted 5 more escape attempts before giving up completely.

17. 360 is a pro at hiding seek.
