Not all are skinny characters, but also chubby characters, such as crayon Shinchan. Designing skinny characters may be more in line with the public aesthetic.

The following is an introduction to animation:

Animation, namely animation and comics, refers to the collection of animation and comics. Combining the first word of these two words into one is called "animation", which has nothing to do with games and is not a technical term.

Animation is a collection of animation and comics, and the relationship between animation and animation is the relationship between inclusion and inclusion, not the same relationship.

All animation and comic works can be called animation works, but it can't be said that animation or comic works are animation, because semantically speaking, animation and comic works are two different art forms, and there is no such art form as "animation", which is just a compound word created by China.

Refer to Baidu Encyclopedia-Animation for the above information.
