Heat the broken almond bark according to package instructions. In a large bowl or a 2 gallon zippered bag, add the popcorn, pretzels, cookies, M&M and Mike & Ike candies. Pour half of the melted chocolate over the snack mix. Line a baking sheet with wax paper and pack the snack mix into the pan. Drizzle with the remaining almond bark and top with sprinkles.
