Mutants anyone?

[welsh]

How about your ideas for mutant monsters? Can we start a threat on that topic?

Yesterday I was poking at the new edition ideas on mutants and flora/fauna. I thought- not enough evil plants.
Today my wife just told me about this plant that causes blisters and blindness. I got to imagine a place where this plant releases spores into the air that causes blisters and blindness- and your group wanders into the region where everyone is blind and blistered.

What are some of your ideas?
