In a large bowl combine the water and lemon juice. Set to the side.
Carefully begin to cut the apples into slices. Using a pairing knife cut two "mouth" like slits into each apple slice. Remove the excess apple. Place apples in the lemon water mixture and let sit in the water for at least 5 minutes.
Remove one slice at a time, rinse with fresh water and pat dry with a paper towel. Begin to create your apple monsters. Use a nut-butter, hazelnut spread, or even jelly for the inside of the mouth. Then use slivered almonds, sunflower seeds, mini marshmallows or even Greek Yogurt Covered Cranberries to fill in the mouths. The sky is the limit to what you can use.
To adhere the candy googly eyes, place a little nut butter or hazelnut spread on the back of the candy and then firmly press into the apple.
Enjoy immediately or cover and refrigerate for up to 2 hours until ready to serve.
