In a large mixing bowl, pour in the gummy bears, Sour Patch Kids, Skittles, plain M&M's, Swedish Fish, and Twizzlers pieces.
Use a large spoon or clean hands to gently toss all candies until they are evenly distributed.
Transfer the candy salad to a decorative serving bowl or leave it in the mixing bowl for easy snacking.
If you have leftovers, store them in an airtight container at room temperature away from direct sunlight or heat for up to one week.
