In a large bowl, mix cookies with cream cheese until combined. Roll the mixture into balls and set onto a plate. Freeze for at least 20 minutes. Place chocolate chips into a microwave-safe bowl.
Heat in the microwave in 30-second intervals, stirring well until it is fully melted and smooth. Coat each truffle in the chocolate and set onto a plate. Decorate with candy eyes and Oreo cookies. Let sit until completely set.
