For ice, prepare one 6-ounce can frozen pineapple-orange juice concentrate. Arrange chewy fruit worms in the bottom of a 4-cup ring mold. Pour juice into mold to almost cover worms. Do not allow the worms to float. Cover and place in freezer for 1 hour or until frozen. Add any remaining juice to mold. Cover and freeze until firm.
In a small punch bowl, prepare the 12-ounce can pineapple-orange juice concentrate according to package directions, using cold water. Stir in the apricot nectar. Add the carbonated beverage, stirring gently to mix. Unmold the ice ring by running cool water over outside of mold; carefully add ring to punch. Makes 10 (8-ounce) servings.
Prepare ice ring and store in freezer up to 2 weeks before using.
