Slip on the white gloves, ensuring any drawn-on black claws align with your fingertips.
- 4
Apply black face paint in large circles around your eyes to mimic hollow, dark sockets.
- 5
Use red face paint or fake blood to draw dripping lines coming down from the bottom of your eyes.
- 6
Put on the Sonic headpiece or hood, adjusting it so your painted eyes are clearly visible underneath.

- Make sure the hood or mask doesn't block your peripheral vision, especially for younger kids wearing the costume.
