I found this font from a Pinkfong Instagram post, and I wonder what font this is.

Brandon Grotesque  Suggeriti da BigD87 
Pinkfong Sans  Suggeriti da BigD87 
Cookie Run  Suggeriti da BigD87 

I think I found it.

First line = original / second line = cookie run

that's why 0% of the voters agree (4 votes)

I think it's a custom font because I posted a similar case and no one has founded the name of it
South Korean media aimed at a younger audience tend to have custom fonts on their social media/designs
(And yes, Baby Shark is Korean, and my case was from the DECO Studio app, which was made by a Korean company LINE.)

I think this font is closer to "Pinkfong Baby Tuxedo". We haven't found the actual font yet.

The search continues. Keep looking everyone, what font it could be, I'm a bit stumped, to be honest.

Looks to me like a modified version of something like Brandon, but what do you think?

Call off the search, gang! The font is found: it is a custom font.

I found a similar one on DeviantArt, not sure if I can provide you a link (not mine btw)
