Steep the hibiscus tea bag in ¾ cup hot water for 4 minutes. Remove the tea bag and allow the tea to cool completely.
In a large punch bowl or beverage dispenser, combine pineapple juice, passion fruit juice, white cranberry juice, guava juice, orange juice, lime juice, and lemon juice.
Stir in grenadine, honey, and sea salt until fully dissolved.
Stir in the cooled hibiscus tea.
Refrigerate the punch base for at least 4 hours or overnight for the best flavor.
Right before serving, slowly pour in the ginger ale and sparkling mineral water.
Add small scoops of pineapple sherbet throughout the bowl.
Add pineapple chunks, strawberries, orange slices, lime slices, frozen grapes, and mint leaves.
Serve immediately while cold and fizzy.
