But we do know what Chip is; he's Light Gaia, presumably a "hyper energy organism" like Dark Gaia. Furthermore, this is only in the Archie Comics, where Chip has been explicitly stated to be a spirit.

Erazor Djinn also called him a rat, so Sonic has also been referred to as such by more than one person.
