What Am I?

What am I?
I have little pricks sticking out of my slimy sometimes sticky body. They help me to grip on to things and they also help me to dig into the dirt. On the inside of my body I consist of three main organs. The first one is my crop, which is the first place where my food goes through. The Crop is a bag like organ that will keep the food that I eat until my Gizzard is ready to chomp up the food that I eat. My next organ in line is the Gizzard which chomps up my food. “How does it do that,?” you ask. Well the Gizzard has stone like things on the inside of it to turn food in to a mulch like liquid.
