[the croc hunter]

Hi again!
I just noticed white dots on my red mushrooms? Is this normal???
It looks like Ick, but I know it cant be.

I have the same thing and they come and go. Hasn't effected the shrooms in the least little bit though. Not sure what it is just wanted to let you know it seems to be common occurance.

ummmm sand?
I know it sounds like a smart a%$ remark but I can't tell you how many panicked people I heard the have a Mandarin with Ick. It's almost always sand... It takes a lot of mistreatment for a Mandarin to get Ick.
