I like those tumescent pod things 
They are berries that fell off the Christmas decorations.
I was gluing something else & had some glue left over,
so I dribbled glue over them.
I was thinking that they might be like Puff ball mushrooms
& sometimes explode. That would sent poisonous spores
out a random distance (D 10 inches?) Perhaps that would happen
when a joker card turns up in a Galactic Heroes game.
Throw a D6. 1,2 = 1 pod explodes, 3,4 = 2 pods & 5,6 =3 pods.
Might even include wind direction (-2" up-wind, =4" down-wind.
What do you think?
