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

Cookie Run  Sugerida por BigD87 

I think I found it.

Bump

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.
