Spread 1 tablespoon of peanut butter over each pretzel, leaving a two-inch "handle" without peanut butter.
Press and roll popcorn onto peanut butter to coat. Sprinkle with sugar sprinkles.
For optional chocolate drizzle, place chocolate chips in small sealable plastic bag and seal. Microwave 30 seconds or until chocolate is melted. Clip small corner from bag and squeeze to drizzle chocolate over popcorn.
Sprinkle with additional sugar sprinkles. Allow chocolate to harden before serving.
