Begin by placing the white and dark chocolate melting discs in separate microwave-safe bowls. Heat them in the microwave at 50% power for 30 seconds intervals, stirring between each until the chocolate becomes smooth and glossy, which should take about 2-3 minutes.

Once your chocolate is melted and smooth, transfer the mixture into a ziplock bag. Cut a small corner of the bag to create a piping tool for decorating your pretzels.

Take your mini pretzel twists and dip them into the melted white chocolate, ensuring they're completely coated. Allow excess chocolate to drip off by gently tapping the pretzel against the side of the bowl. Place them on a tray lined with wax paper and chill in the refrigerator for about 3 minutes or until the chocolate is set.

Once the white chocolate has hardened, use the piping bag filled with melted chocolate to pipe little faces and add sprinkles for eyes and pink heart sprinkles for noses. Return them to the fridge for another 5 minutes.

Dip more pretzels in the white chocolate for your sheep creations. While the chocolate is still wet, coat them generously with nonpareil sprinkles and then use the piping bag with dark chocolate to add detailed eyes and a mouth. Chill again for about 5 minutes.

For the remaining pretzels, dip them in your prepped dark chocolate, ensuring they are well-coated. Sprinkle your desired mix of pastel sprinkles on top or drizzle them with previously melted colored chocolate. Chill for an additional 3-5 minutes.
