Cut a piece of construction paper to be the exact length of your paper roll. Spread glue from a glue stick onto one side of the paper. Line up the ends of the paper with the ends of the paper roll, then wrap the paper around the roll so it's completely covered.
Using a glue gun or glue dots, attach one of the googly eyes to the middle of one of the larger pom poms. Repeat for the second googly eye and second larger pom pom. These will be your dragon eyes (you should have two eyes).
Using a glue gun or glue dots, attach each of the dragon eyes to one end of the paper roll.
Using a glue gun or glue dots, attach the two smaller pom poms near the other end of the paper tube to make the dragon's nose.
For the fire, cut scraps of red, yellow and orange tissue paper to be long pointy strips, about 9" or 10" long.
Spread some glue from a glue stick onto the straight end of one of the strips of tissue paper, then attach it to the inside of the paper roll under the dragon's nose. Repeat, and keep gluing tissue paper to the inside of the paper roll as you work your way around the roll. Only glue tissue paper as shown in the photo. Don't glue tissue paper all the way around the bottom of the roll (under the nose). Gravity will pull down any tissue paper there and it won't move when you blow in the paper roll.
Your paper roll dragon is complete! Take a deep breath, put your mouth on the end of the paper roll and BLOW!

Notes
Make your dragon green, red, black, purple, blue, white or multicolored. Who says dragons have to be one color?!
