Snail Diarrhea?

[kalamari]

Hello! I've had quite a few grove snails for two years now but I've never seen their feces look so runny? They appear to have the texture of bird droppings when normally they come out like silly string. I was wondering if any of you have had similar experiences.. Is this is normal or healthy? 

Here are some photos (sorry for the large size I didn't realize I saved them so big) :

ok this is veru interesting for me, as it happened several times to mine! it is not feces in my opinion, it is a kind of mucus that is sticky at the moment they produce it, but will become dry and "dusty" the day after... If anybody have know for sure what it is, I would like to hear as no one yet was able to give me a final answer.. It looks like the substance that they produce when they have to build the epiphragm, in my opinion it is somehow related! I will enclose a pic later and hope anybody can help!
