These are pictures I collected from Google so all rights go to the amazing artists, I'm just using them as an example until I can find the focus to draw him myself.

Someone said this in an Ao3 fic, idk where, but it's been in my head since then. I have a few head canons about it that I put on my board but I'll talk more about them here.

He has a little cow tail with a tuff of fur at the end (see bottom left) that he can wack people with.

He can kick really hard, idk if he'd have hooves like Puffy does (I think she has hooves) but it doesn't matter because he can still delete your knees with one solid kick.

He has vitilago, which was the first sign that he wasn't a goat like Schlatt was. Most of his skin tone stays the same, but now he also has these splotches of white, yellow, and pale brown. His firework scar didn't change ofc, but now it's not the only big mark he his on his face. He was real self conscious of his spots at first, but Ranboo and Techno (who I head canon has subtle pink vitilago) both told him there's no reason to feel self conscious, he's not the only one with a skin condition.

Speaking of Schlatt, he doesn't have big ole twisty horns, they just stay nubs. They do get a little bigger, and they get darker because they harden and become less sensitive, now he can actually use them as weapons, not that sweet Tubbo would ever (I mean he might, he can be scary tbh). They also twist in towards each other as they grow, like actual cow horns would. Luckily he isn't a big horn, because then they would just shoot out horizontally and he'd never rest again. (Google long horn, omg those poor animals)

Unrelated, but Tubbo and Quackity bonding over having a huge face scar, both because of something Schlatt made Techno do, it needs to exist please. I want wholesome step dad quackers.

Now for the biggest head canon I have, which I really want to make into a story. So for the sake of this, let's say that Mooblooms are classified as both an animal, and a type of plant. (The vegans, omg the vegans) Because of this, Tubbo is also technically kind of a plant. A flower, to be more precise. Tubbo is a flower. Therefore, not only can Ranboo pick him up, but so can Shy and other Endermen, because flower. And they do pick him up, often, because flower yoink. Tommy, Ranboo, Nikki, and maybe Jack too have to always go off and rescue Tubbo from Shy or stray Endermen who see him and wanna just keep him lolol.

Also, he smells like flowers all the time now, so bees absolutely love him, and will follow him everywhere. Unless he tells them to go home, because they listen to the nice flower boy.

Ranboo and Tommy were the first to notice, but Tubbo smells like different flowers depending on his mood, so they know when's he's happy because he'll smell like sunflowers or something, and when he's sad he smells like corn flowers, and when he's sick, he smells like freshly cut grass. (Not just because sick is like green, and grass is green, but the smell of cut grass is actually the grass making a chemical because it's hurt and screaming and it makes that smell, so when Tubbo is hurt he smells like screaming grass)

The little different Mooblooms with different colors and flowers are adorable, but I do think he'd be a yellow moobloom, because bees.

His hair would change, the top would become blonde, like it's been sun bleached. So the bottom of his hair, and his little tail fluff with stay dark brown, but we can still get blonde Tubbo.

Idk if he would grow flowers, maybe out of wounds if he's hurt, that's a thing right? Or if he's really happy, or maybe both of those things, flowers just sprout from him when he's feelings a very strong emotion, and the type of flowers depends on the emotion. Flowers have meanings already, so someone can probably do the research there and make it logical, not that any if this is logical, but you know. You get it.
