Line a baking sheet with plastic wrap or wax paper.

Melt pink candy melts in a microwave-safe bowl according to package directions. Do the same with blue and purple. Pour blue and purple candy melts into squeeze bottles or ziploc/piping bags with a small tip cut off.

Pour melted pink candy onto the baking sheet and spread into a rectangle, about ¼-inch thick.

Drizzle with blue and purple candy. Tap baking sheet against the counter or table to help the candy flatten out.

Immediately top with sprinkles and decorations. (If you're going to use gold foil, make sure to leave some empty spaces where you'd like to put it. Then once the bark is dry and set, press on the foil.)

Place baking sheet in the fridge for about 30 minutes to and hour for bark to set. Once bark is hard, use a knife to cut it into pieces, or use your hands to break it up.

Store in refrigerator until ready to use.

Spread frosting around the outside of the top of the cup you'll be using. Cover in sprinkles. PLace cup in the freezer. (This will keep your shake cold longer!)

Place about 4-5 large scoops of ice cream in a blender. Add about ½ cup diced strawberries and ¼ cup raspberries. Add ½ cup milk. Blend until smooth. Add more ice cream or milk depending on your preferred consistency.

Pour shake into the glass. Top with whipped cream, stick on some pieces of unicorn bark, cotton candy, rock candy, and sprinkles!
