I collect molds, spores and fungus

I read a while ago a list of 1 HP monsters that you could use in your adventures, I decided to come up with something a little similar.  Know don't think that these are easy to defeat creatures, because they are not, they do however have a weakness.

Sputtering Spores Of Greenswath 

The sputtering spores of greenswath (so named because this was the first village they were discovered in) are a swarm of greyish spores (1HP).  They inflict choking damage, any PC caught in there midst will soon start to choke and cough, suffering from lack of Oxygen.  PC's can save vs Breath Attacks for half damage.  Normal weapons do no damage to them whatsoever.  Magical weapons and fire will inflict normal damage upon them.

Flinging Fungus 

Flinging fungus are large organic fungis shaped in a semi oval pattern, they are about 3 inches deep, and on their under belly they have a gripped like substance that allows them to attach to walls, floors and ceilings.  One of their favorite tricks is to fling themselves from the ceiling landing on unsuspecting PC's.  Because of the organic nature of their makeup, they can be harmed by normal weapons, but they are extremely quick.  They tend to leave a slimey residue on the ground which makes it difficult for PC's to catchup with them.  (DEX Check required to give chase).
