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