Allow cake to cool after baking according to box directions.
Crumble entire cake in a large bowl with a fork.
Add frosting and work it into the cake crumbs with your hands until it forms a ball.
Roll dough into 1-inch balls and place them on a baking sheet lined with parchment. Freeze them for 1 hour.
Melt chocolate bark in a microwave-safe cup that cake balls can be dipped in.
Using two forks, roll each cake pop in melted chocolate, allowing excess to drip off. Place dipped cake pops on a baking sheet lined with parchment paper.
Before chocolate hardens, place an Oreo on the backside.
Carefully place the eyes, nose, and mouth in place. I like to use a tweezers. And if the chocolate hardens too quickly, you can add a bit of melted chocolate on the back sides of the eyes, noses, and mouths to act as glue.
Finally, dip the tips of each candy corn in melted chocolate and place three of them on each turkey to create the feathers. You may have to hold them for a bit until the chocolate hardens.
Chill before serving.
