In a very large bowl, stir together pretzels and cereal. Add candy and marshmallows and stir together.

Spread mixture evenly onto large baking sheet.

Cut licorice Twizzlers into small pieces and add on top.

In 3 separate microwave safe bowls, melt chocolate for 30 seconds, stir and continue heating for 10-20 seconds at a time, stirring after each heating, until chocolate is almost melted. Continue stirring until smooth.

Transfer into plastic squeeze bottles. This is optional, but much easier to add the chocolate. You can also use piping bags or just drizzle with a spoon. Drizzle white chocolate, then add red and blue melted chocolate.

Immediately add sprinkles. Let set about 10-15 minutes to harden.

Break into pieces. Store in airtight container until ready to serve.
