I've noticed it's becoming a bit of a fad now in animation to have a character thats hard to understand and no way we we'll ever undrstand other than the fictional characters.
I don't know if this will be hard to give a description for, I'm sorry if this is more of a list thread but we can try. Feel free to also discuss the topic. It'll be fun discussing it too
Some examples are
Kenny Mcormick from south park- The parka mumbles his words and we have tried decoding what he may be saying forever. Yet only his friends can somehow tell what hes saying.
Shnitzel from Chowder- This is an example of a growing fad I noticed on Cartoon Network with characters saying only one word yet the characters can hear them clearly.
Coco from Fosters Home for Imaginary friends- Basically the same situration as shnitzel from chowder. Only difference is she repeats "coco" numerouse times.
