Original
Chip is an American Cockroach of an unknown name and origin. She is not a Mobian race, just an insect.

Mobian
Chip is small, round, and very cute. Someone who has a reference on hand should probably expand this.

Original
She's very expressive with her antennae. Due to not being able to talk, she can only talk by body movements. She tends to be around any type of Sonic for comfort at any given time.

Mobian
After getting herself a sweet new voicebox, she's taken to babbling and repeating things she's heard, similar to how Lah spoke while re-learning how to communicate she's also become very curious, wanting to learn more about her surroundings now she can interact with them differently.

Ess
Ess and Chip are very close friends, at least it appears to be. She spent many months with Ess while he was imprisoned and never left his side.

Trivia

 * During an adventure into the Depths, she was shown that she has thoughts and ambitions, despite being just a bug. She depends on Ess with her life.
 * Her consciousness was shown to be a sunset ocean with a sea of "red and yellow liquid."
