Line a baking sheet with parchment paper and set aside.

Place popcorn into a large mixing bowl. Melt chocolate chips by placing into a microwave safe bowl and microwaving for 60 seconds on 50% power. Stir well. Continue to microwave in 20 second increments at 50% power and stir well until smooth. Pour over popcorn and mix well to evenly coat. Spread onto prepared baking sheet and immediately sprinkle with valentine sprinkles. Let set to harden.

Once popcorn is set, break apart and mix together with pretzels and M&M candies.
