Blowgun Idea... Who says you have to shoot something from your mouth?A good gust of air through a bamboo straw could knock an adventurer down, (without fear of lawsuits from consumers).
Or... you could still shoot a small plastic marble through a tube at an adventurer on the board. Just make sure the end of the tube that goes into the player's mouth is smaller than the marble, so it can't accidentally go into their mouth.
Think spitwads through a straw from high school, except with a thicker straw (just as narrow, though) and a tiny plastic marble instead of a tiny wad of paper. :)
