Identify hitch hikers please

This first picture is from farther back. Sorry about the image quality.
The critter is dark purply-red, and BIG, perhaps 4" . It comes
from a 'bulb' and has a longish stalk with the crown waving around.
It just popped out of the rock.


The rock has lots of these guys. Will they bother the mushrooms?



I hope they're good guys!
