Should look something like this instead:
```
viewers(user) << "<span class='danger'>[user] puts [src] on their head and stretches the bag around themselves. With a sudden snapping sound, [src] shrinks to \his original size, leaving no trace of [user].</span>"
```
Used ```their``` since I'm not sure whether ```\his``` will work properly (referencing ```[user]``` instead of ```[src]```), since i have doubts about how well byond's grammar parsing works (if at all), though test it out and see
