I do actually! Here's a post where I discuss my headcannon

And a small list of background mixels I headcannon as female (or just gender fluid in two cases)

Fridjerk - They/Them (cis)

Pyrope - She/It (Trans)

Booger - He/They (I'M LEANING ON EITHER FEM OR NB HERE SO HE'S GOING HERE)

Hurtz - Any (Genderfluid)

Banjoe - Any (Genderfluid)

Scrud: Was I too fast? Bitch, no.

Booger: *Angrily stares at the winner while in second place*

Fridjerk: *Meticulously types in kashoot me and blows a chefs kiss*

Jamzy: *Is in the game as four different people*

Boldurr: *Reads the question six times before answering*

Snax: hOw aM i sUpPoSeD tO kNoW tHiS wE lEaRnEd iT tHrEe wEeKs aGo-

Camillot: *Sweats anxiously as they hit first place halfway through the game*

Freezi-Breezi: Secret classroom superpowers? Obviously.

Hotstuff: *Screams out wrong answer*

Squiddo: *Dances along to the music like a maniac*

Combustor: what the fuck what the FUCK WHAT THE FUCK WHAT THE FUCK-

Banjoe: *Puts head down halfway through and refuses to continue playing*

Mixadel: *Wasn’t playing, created the kahoot and watches, entertained*

Steemur: *Hits computer while crying*

Me, giving the show more She/Hers: It's free real estate.

Pyrope is a wolf in a rabbit’s body! This lava handed mixel may look like an absolute sweetheart, but the pranks only start from there. If she’s not indulging in comics or writing in her diary, she’s with her best friends planning a new attack. However, once separated from her pack she shrinks back and runs away. It’s unknown whether she’s shy and impressionable by nature, or if she does this to seem innocent. Many think it may be both.
