First, cut the middle out of each quarter of the apple in order to create a mouth. Don't worry about it being perfect, as you are filling this gap with almond butter anyway so if you cut too deep, you can always cover it up and you won’t even be able to notice.
Coat the inside of the gap where you just cut with a filling of almond or hazelnut butter.
Place sunflower seeds on the top of where the "mouth" is to resemble the teeth.
Place 1 sliced strawberry inside the mouth to resemble the tongue.
"Glue" each eye above the mouth, using a dab of almond butter to make it stick in place.
Serve your monsters and enjoy!
