In a large mixing bowl, scoop the thawed Cool Whip and add the sour cream. Stir until smooth and free of lumps, about 2 minutes.

Drain the maraschino cherries, pineapple tidbits, and mandarin oranges thoroughly. Pat dry with paper towels and set aside.

Fold in the dried fruits and mini marshmallows into the whipped cream mixture until evenly coated.

Transfer the mixture to an airtight container and chill in the refrigerator for at least 1 hour.

Serve the chilled Ambrosia Salad in individual cups or a large bowl, garnished with additional maraschino cherries.
