In a large saucepan, melt the butter over medium heat.

Add the mini marshmallows and stir continuously until they're completely melted and the mixture is smooth.

Remove the pan from the heat, then quickly add the Rice Krispies cereal, vanilla and salt and stir until it's well coated with the melted marshmallow mixture.

Using a buttered spatula or your hands (make sure they are clean and well-buttered), press the mixture into a buttered 9x13-inch baking dish.

Let it cool and set for about 1 hour, then cut into squares.

Melt the white chocolate and divide it into three different bowls.

Now add the food colouring of your choice and mix well.

Dip each square of Rice Krispie treat and place the sugar eyes on top.

Let the chocolate set and serve!
