A SPIKY LITTLE COMPLICATION
Orange Burr.
Leave it outside.
It can brush past creatures safely. Your loop still needs to give it some room.
An obstacle, not an armed hunter
Orange burrs do not damage the swarm by touching it. Catching any armed or orange burr inside your loop costs a life. Use an open line to separate it before making the catch.
DON'T JUST READ ABOUT IT
