Today is Monstrous Monday, as declared by Tim Brannan. Here then is my contribution, from my almost finished Lottery Dungeon adventure setting:
These strange ‘monsters’ are really an alien fungus that feeds on decayed flesh, before releasing spores. They resemble balls of orange spikes, about the size of a human head, and bounce along in search of living beings: they then hurl towards them, intent on paralysing their victims and slowly excreting an acid that eats away at the flesh, allowing them to absorb the liquefying flesh.

These fungi begin combat by charging into their opponents, dealing double damage (2d8) on a successful hit, and forcing the target to make a save versus petrification or be knocked prone; a successful hit also causes paralysis for 2d6 turns, unless a further save versus paralysis succeeds. The fungi then sit attached to their prey, slowly digesting them, automatically dealing 1d6 acid damage per round; they can be easily removed, without harming the victim, but the fungus will try to reattach by attacking the following round.
