Lightly grease baking sheet(s); set aside. Preheat oven to 425°. If using loaf of dough, divide thawed loaf into 12 equal slices. If using rolls, they are ready to use once thawed. On a lightly floured surface, pat or roll each piece of dough into a circle 4-5 inches in diameter. Place dough rounds on prepared baking sheet(s) 2-3 inches apart. With clean scissors, cut 6 equal slices to bottom half of each circle (each slice should be approximately 2 inches long). Pull and twist each slice several times. This will form the legs of the jellyfish. Brush each jellyfish with melted butter. Place two olive slices for eyes. Cut one olive slice in half for mouth. Bake immediately in a preheated 425° oven for 10 minutes or until golden brown. Remove from oven and brush with melted butter or margarine. Remove from pan to cool on wire rack.
