Begin by melting the white chocolate using a double boiler or a microwave. Heat in 30-second intervals, stirring thoroughly after each burst until smooth.

Carefully split each Oreo cookie in half without breaking the cream filling. This allows you to add the decorative elements.

Take two yellow M&Ms and press them into the cream of each half to resemble ears.

Carefully immerse the top half of each assembled Oreo into the warm melted white chocolate, ensuring it is well-coated.

Place the dipped Oreos on a lined cookie sheet and transfer them to the refrigerator for about 10 minutes to chill.

Using a small dollop of melted white chocolate, attach a white chocolate wafer as the nose. Place a blue M&M atop the wafer.

Use a dab of melted white chocolate to secure two small candies or chocolate chips above the blue nose as eyes.

Once decorated, return the cookies to the refrigerator and let them chill for an additional 30 minutes.
