Preheat oven to 275 degrees
Place pretzels on a lined baking sheet.
Unwrap Rolos and place on top of pretzels.
Place in oven for 1-2 minutes or until Rolos look soft. Do not cook too long. You want the Rolo to keep it's shape.
Remove from oven and add a candy eye to each Rolo.
Place in refrigerator to harden for about 10 minutes.
