Make eyes. Using fondant roller with purple guide rings, roll out medium blue, green and teal fondant, separately, to 1/8 in. thickness.
Using smooth side of round cut-outs, cut out two medium blue circles with “B” cut-out, two green circles with “C” cut-out and two teal circles with “D” cut-out.
Using Water Brush, attach one teal circle to center of green circle, then attach green circle to center of medium blue circle. Repeat for other eye. Using “E” cut-out, cut out center of each eye.
Roll two 1/2 oz. balls of yellow fondant. Using Water Brush, dab water on inside of cut center circle of each eye. Position yellow balls in center of eyes, flattening ball until it fills the circle fully.
Using fondant roller with pink guide rings, roll out black fondant to 1/16 in. thickness. Using “F” cut-out, cut out two circles. Using Water Brush, attach black circle to yellow part of each eye, cutting through all three layers.
Position eyes on cake. If icing on cake has crusted, pipe remaining icing in any color on back of each eye before attaching to cake.
