How to put it together
- 1
Put on the royal blue jumpsuit or matching blue shirt and pants combo.
- 2
Cut a large, elongated oval out of the yellow felt and fabric-glue or pin it to the front torso for the yellow belly.
- 3
Apply dark blue fabric paint or glue dark felt strips along the sides of the torso and arms to mimic the cleaner wrasse stripes.
- 4
Cut out a fish tail shape from the foam board, cover it with blue and yellow felt, and secure it to the back of the waist.
- 5
Construct Oscar's face on the blue beanie using white, black, and green felt circles for his large eyes, and pink felt for his thick lips.
- 6
Put on the decorated beanie and finish the look with simple blue or black sneakers.
Makeup & hair
Keep your hair completely tucked under the blue beanie or hood. If your face is visible, you can apply blue face paint around your forehead and cheeks, blending into yellow near your chin.
