Mushy appeared at the same time Keytar started to leave. In Pavlov, they are the same height, use the same weapons and hold them the same, play in the same way, both eco with knives and throw them accurately, etc. and have never been seen in any game together*. The only thing that doesn't match is Mushy didn't use FBT in VRchat, but that could be intentional. It doesn't seem very likely it's all a coincidence.

* the one time they 'were' was drunk Pavlov when everyone was switching names as a joke and Keytar was never in the server.
