Mix the cream cheese with the crushed biscuits in a large bowl to make a smooth paste. Use your hands: the kids will love it! Shape the mixture into small balls the size of a lollipop: don’t overdo it or else they will fall apart. Then spear them with the lollipop sticks and put by.
To melt the white chocolate, heat a pot of water (but without boiling) and put a glass bowl with the chocolate inside. Stir over low heat until it melts. Dip the lollipop into the melted chocolate. Before it sets, stick a Lacasito or M&M onto it and dot a small amount of the chocolate spread in the middle to make a pupil. Stick the lollipops into the cut pumpkin, as if making a hedgehog.
