Sack Boogies

...It's a PLATELET. It's a low-power, weakling of a sackboogie. You are in quality armor designed to protect from sackboogie attacks.
It's scarcely more threatening than a keuriglett, and at least those can scald their target if desperate enough.
One lone PLATLET really can't do much more than harmlessly smack into your visor, can it?
Well, it can obstruct your vision, for starters. Not to mention it probably has friends. And, uh. That would be considerably more troublesome.
Just grab it and hold it in place until it calms down or something.
