01 - Line a baking sheet with parchment paper to prevent sticking.
02 - Pulse Oreo cookies in a food processor until fine crumbs are achieved.

06 - In a heatproof bowl, melt chocolate over simmering water or in the microwave with 30-second intervals, stirring until smooth.
07 - Using forks, submerge each chilled ball in melted chocolate, letting excess drip off. Return coated truffles to the baking sheet.
08 - Quickly press two candy eyes on each truffle before the chocolate hardens.
09 - Break pretzel sticks in half. Insert four pretzel halves into each side of the truffles to resemble legs.
10 - Sprinkle with colored sugar or sprinkles if desired for festive appearance.
11 - Place finished truffles in the refrigerator for minimum 30 minutes until chocolate exterior is fully set. Serve chilled or at room temperature.
