Preheat oven to 350 degrees F. Line a baking sheet with parchment paper and set aside.
Pop open the cinnamon roll tube and place them on the prepared baking sheet. Find the end of each and pull away from the center to create a "head" for the snail. Bake according to package directions until golden brown.
Remove from oven and allow to cool completely. Stir the icing that comes with the cinnamon rolls with a few drops of green food coloring and then transfer to a small sandwich bag. Snip the end off and then swirl a bit of icing onto each cinnamon roll.
To create the eyes, press a mini chocolate chip onto the side of each mini marshmallow. Skewer them with a toothpick and then place two onto each cinnamon roll. Serve immediately.
