Yeah, their color-change capabilities aren't quite what they're cracked up to be (though still a nifty and extremely rare ability, even if used for a novelty purpose). However, its other traits are still fairly noteworthy: perpendicular vision capable of covering several angles, long prehensile tongue, and the ability to grip with any of its legs. I agree, an 8 or 9 seems quite suitable for it.
