Break off a hunk of black clay that is about the size you'd like your final niffler to be.
Separate black clay into portions: 4 pieces about 1/10 the size of the hunk, one piece 1/3 the size of the remainder.
Shape the biggest piece into a fat cylinder and flatten the "front" and "back" forming the body.
With the 1/3 portion of clay, roll it into a ball, flatten the back, then elongate the front, forming the head.
With the four remaining 1/10 portions, form small cylinders and place on the body as arms and legs wrapping around toward the front.
To make the beak, use the orange clay to form a wide, long triangle with a rounded front and fat back the same size and width as the face.
Place beak on the face.
Make 2 very small off-white balls with the off-white clay and mush them onto the face above the beak.
Make 2 even smaller black balls of black clayand mush them onto the white circles you just placed.
Form a tiny ball of orange clay and roll it in the glitter.
Place this tiny golden nugget in the niffler's hands.
Trim the eye pin to about 1/2-inch long.
Slide eye pin into the top of the niffler's head or wherever you want.
Place the snitch into the oven on wax paper for 30 minutes.
Remove from the oven and allow niffler to cool completely.
Seal the niffler.
Attach a jump ring to eye pin .
Thread necklace into jump ring.
Enjoy!
