Mix the rice bubbles, icing sugar, coconut, copha and cocoa powder in a large saucepan. Place over low heat until the copha has melted and all the ingredients are well combined. Allow to cool slightly, so the mixture can be handled.
Take 2 tablespoons of the mixture and shape them into mice. Use 2 brown m&m's or smarties as ears. Use a thin strip of liqourice as a tail. Cut 2 small bit of liqourice as eyes.
