Chukk'Chee:
Sounds about right.
As for the name of the planet, let's call it Ch'k Ch'k. (In English, that would mean 'Burrow' or 'Warren'.) As you can tell, Chukk's native language is a lot of chittering noises, like a chipmunk or squirrel.
Got it.
In Scav (which is probably just what MegaCorp, Inc. calls them), the planet is Ch'k Ch'k.
To MegaCorp, it's just P-CMM-21185.
Human employees of MegaCorp, Inc. have taken to just referring to it as "Warren."
The rest of the galaxy probably doesn't think about the planet at all... though they may start one day soon...
Okay, time for me to go advertise...
