You didn't answer my question as to why you changed to word order. The japanese thwiki uses 河童 and only 河童. That source is inherently more important than pixiv.
"mob" means "mobile object", just so you know. It's not a term we use to describe extra characters.

Actually, that use of "mob" is not what is being thought of. Before that neologism came into use, the word was used to refer to a large group of people. A "kappa mob" would not be a kappa programmed to move around an area of a simulation, but a whole bunch of kappa.
