Biologically they have no gender, but mentally they be males, females, gay, straight, what have you, the same as ponies. However their shape subconsciously mimics their mental state. He thought he was female at one point so he appeared female, and when he came out as male his appearance slowly shifted over time to appear male :D
 
And, you can probably tell I’m super unfamiliar with the whole topic of transgender and all that, since I probably got a million terms wrong and probably didn’t word it very well, so hopefully you get what I’m saying XD

Mattie was a filly when he was younger, but as he grew older, he decided he’d be happier as a stallion, so he just became one (which is a pretty simple process for a slime pony, as there’s no biological difference between males and female of their species).

@Badumsquish  
Mattie is a colt or made? This doesn’t make sense…

@mjangelvortex  
Love you too.  
Possible homo.

@mjangelvortex  
:D

He’s adorable.
 
@Background Pony #DFB2  
I love you all.

@Background Pony #DFB2  
Lol yeah, that’d make things a lot easier. Some goo ponies do have more androgynous appearances, but for the most part they’re male or female. They look and act like ponies because their evolution from just primitive slime creatures into what they are today was influenced by ambient pony magic. The only real reason they have genders and preferences at all, along with pony shapes in the first place, is because ponies do :D

cool

Ba-dum-squish.

Ba-dum-tssh

@Background Pony #F559  
That comment is both accurate and pretty funny.
 
@Badumsquish  

If only it were that easy for all non-binary people.  
(Also, considering how goo ponies aren’t locked in as mares or stallions, I imagine most of them probably wouldn’t completely identify as completely male or female, and many of them would likely appear mostly androgynous.)

@Badumsquish
 
Yay~! hugs the blue goo pony

@Background Pony #DFB2  
Indeed :D
 
@KW117  
Basically they have no biological sex, but they do have genders. Or whichever word means which, honestly I don’t really know. Physically they’re genderless but mentally they’re male or female or whatever. Their “true” appearance reflects who they are mentally but can change over time. As he grew up and came out as identifying as male, his true appearance changed to reflect it :D
 
@Secretly a Yordle  
Good news, because all goo ponies are huggers :D
 
@Napsack  
I wanted to have one of my goo ponies come out as trans, so I used the one who was a filly last time I drew him :D
 
@Background Pony #7345  
:D
 
@Background Pony #F559  
XD

Gooponies are so cool

I love him <3

Nice

Is the tradition now to draw this character only once every 3-4 years at minimum?

@KW117  
It varies from one trans person to the next, but from what I can tell, most tend to prefer you use their current pronouns in most or all situations.

Wouldn’t mind hugging and sinking into him

And yet still just as adorable :D

Handsome goo pony.

@Background Pony #DFB2  
technically wouldn’t that be… “she” grew up to be a fine young stallion?  
IDK how gender things works in general, the whole goo pony thing just adds a whole extra layer to the confusion.

aweeeee, he’s a cutie

He grew up into a fine young stallion.
