I'm watching a streamer who used stickers to label all her mannequins, but the stickers disappear when the mannequins activate. This confused her into thinking the activated mannequins were "impostors". It would be a neat detail of continuity if the stickers stayed on the mannequins.
Similarly, a nametag given to Kerfur-O will disappear when activated. I can't give my boy a funny name :(
