I usually bake these in little muffin cups and garnish it with strawberries and a little honey, but I used all my muffin cups (and this week on Guam, the strawberries shipped in didn't look too great). :P It works anyway. They call them "ghost" puffs because the marshmallow disappears and leaves an empty cavity of barely-visible-yummy inside. :)
Preheat oven to 375 and Separate crescent dough into eight triangles.
In a small bowl, combine sugar and cinnamon.
Dip each marshmallow in butter to coat.
Wrap in crescent dough. Place marshmallow on wider side of triangle, fold corners and roll. pinch ends of dough to make sure marshmallow is sealed nicely inside. *Make sure to pinch them well because the marshmallow will leak out!
