How to put it together
- 1
Put on the royal blue furry onesie and zip it up comfortably.
- 2
If your onesie does not have built-in eyes, securely attach large DIY googly eyes to the top of the hood using hot glue or safety pins.
- 3
Put on the royal blue knit gloves to keep your hands matching the rest of the blue monster body.
- 4
Apply a light layer of blue face paint around your eyes and nose if you want your face to blend seamlessly into the hood opening.
- 5
Carry your plush or cardboard chocolate chip cookie prop in one hand, or tuck a few real cookies into your pockets for snacking.
Makeup & hair
No complex hair styling is needed as the hood covers your head. If your face is visible, apply royal blue face paint around your eyes and cheeks, leaving a black circle around your mouth to mimic Cookie Monster's wide-open mouth.
