Open the paper bag and paint each side pink. We stood our bag up over a plastic bottle to make it easier to paint.
Crumple up scrap paper into a ball or use scraps from your recycling bin like bubble wrap. Drop the paper ball inside the bag.
Gather up the bag under the bag and tie a piece of yarn tightly around it to hold the paper ball in the bottom of the bag.
Cut the paper bag into strips. You now have the octopus head and octopus tentacles! Glue on the eyes and you're done!
