In a medium heat-safe bowl, melt the candy melts in the microwave for 30 seconds on 50% power. Stir and repeat microwaving until the chips are completely melted.
In a large bowl pour the candy melts over the Chex. Stir carefully until the Chex are coated. Spread the mixture out over parchment paper or wax paper. Add the sprinkles on top and let cool and harden, about 1 hour. Break apart, add the Trolli Sour Bite Crawlers and either serve immediately or sore in an air-tight container.
