Spread out the popped popcorn on a baking tray. Then break up half of the pretzels and spread both the broken pieces and the whole pretzels over the top of the popcorn. Sprinkle M&Ms on top.
Melt the candy wafers in the microwave in increments of 30 seconds, at 50% power until they are melted and smooth when stirred. Drizzle the melted chocolate over the popcorn mix.
