The article is much better in my opinion, but there are minor tone issues that I'd have to address
SCP-3077's primary anomalous property is that it is animate,
you could simply write it as "SCP-3077 is animate,"….
and control them in a jerky, puppet-like manner.
I feel this is, hmm, more like "stiff" manner? Eh this one's not really that bad,you could probably left it.
However, she does not appear to possess any ability to control either
More like, "However, PoI-3077-1 has not demonstrated ability to control these instances" or something?
Again, these advice are completely optional and the skip is good enough as is. Best of luck.
