Start with a clean, dry rock. Paint a triangle-shaped snout in white. Let dry then paint a second coat as needed.

Outline the snout and fill the entire rock surface in a triangle shape using gray.

Outline the outer rim of the white snout with light gray.

Paint two eyes at the sides of the head with black.

Mix a bit of darker grey and paint crescents around the outer sides of the eyes.

Paint an oblong mouth outline using red. Mark out teeth using red and fill it in. Wait till it dries a bit and paint a second coat as needed.

If needed clean up the snout with some additional white paint.
