If you're looking for an earth-friendly treat that may cause a bit of fright go with ghost lollipops. Toddlers love projects so enlist your lil ones help in wrapping each individually wrapped organic sucker in a sheet of recyclable tissue. Tie it off just under the candy with a piece of string, ribbon, twine or raffia found around the house. Then have your child use a black pen to decorate the flying friends faces with good or ghastly expressions.
For a clever way to carry the treats to a school party or to line them up for trick-or-treaters, have your youngster paint the upside down empty tissue box with some eco-friendly paint. After drying it overnight, puncture small holes in the top and insert the ghosts.
