snails

I was cleaning in the garden some days ago and was putting a lot of weeds away in a paper sack(imagine how much work I did that I filled up the compost?.), that after I came back from lunch I saw a lot of snails escaping from the paper sack. I was not able to take the actual picture but the next day, I took the picture of the sack , draw the snails and enhanced it in photoshop.
