Melt the white and dark chocolate melting discs in separate microwave-safe bowls on 50% power for 1-2 minutes, stirring every 30 seconds until fully melted and smooth.

Dip mini pretzel twists into the melted white chocolate, ensuring they are well-coated, then place them on a parchment-lined baking sheet and chill for about 5 minutes.

Use remaining melted white chocolate to pipe faces and ears on the pretzels, attaching candy eyes and pink heart sprinkles for noses.

Dip another batch of dipped pretzels in white chocolate and sprinkle white nonpareils over the wet chocolate to create a fluffy sheep appearance.

Dip remaining pretzels into melted dark chocolate, sprinkle with colorful toppings, and allow to chill until chocolate has firmed.

Drizzle melted dark chocolate over already coated pretzels for a decorative swirl effect.

Chill all pretzels for at least 5 minutes to fully set before serving.
