There’s already a thread for this topic:

Fungoid, Plantoid creatures?

I’m a big fan of Warhammer 40k, and one of the species in this series are Orkz, which are humanoid and sentient colonies of fungi. I think it would add interesting flavor if we could see mobile and sentient fungoids or plantoids. What is your opinion on this?
