You know, I’ve seen many times that Pinkie Pie gets depressed … both in the series and in the comics, has gone through many things, like when Twilight Sparkle shouted at her in the movie, but that did not make her gray … However, in season 1, she became Pinkamena when she thought that the mane “5” did not want to be her friends … and here it was to tell her that she no longer played that musical instrument, … and if it is not depression or sadness , it is for a lot of fun or for getting angry or for another emotion.
 
Pinkie Pie always takes her emotions to another level … to a very extreme one…
 
Sadness or depressed (This would be another example)  

 
for getting angry  
 
 

 
for fun  
 
 

You Technica lly forgot the one from the movie.

Derpamena??

INDEED. Too much joy and excitement can make you stop thinking properly, and may even lead to insanity.

Thanks for the explanation!

So much happiness.

cliff notes: It’s referencing the California Institute of Arts where many prominent post-2010 animators have graduated from and how apparently the vast majority of them (as well as animated shows of now) all seem to have the same “peanut-shaped mouth smile”. Many animation fans have criticized the style for being lazy and saturating popular culture.

The smiles look similar to the ones used in the CalArts style.

we’re all going to die
