How to put it together
- 1
Select your style: choose either the classic blocky cardboard DIY method or a comfortable printed fabric jumpsuit.
- 2
If going DIY, measure and cut arm and head holes into your main torso box, ensuring it fits comfortably over your shoulders.
- 3
Paint the torso box and the square head box in your chosen avatar colors (like bright blue, yellow, or green) and let them dry completely.
- 4
Draw and cut out rectangular eye holes on the head box, then hot-glue black mesh fabric on the inside so you can see out.
- 5
Paint a simple, blocky smiling face on the front of the head box using black and white acrylic paint.
- 6
Put on your base clothes (the Roblox logo shirt and pants), slip on the torso box, place the head box on, and slide on the blocky hand covers.
- 7
Equip your plastic toy accessory or cardboard sword to complete the gaming avatar look.
Makeup & hair
No makeup or hair styling is needed if you are wearing the full box head mask. If you opt out of the mask, style your hair in a blocky, spiked wig and use yellow face paint to mimic the classic yellow Robloxian skin tone.
Roblox for couples, groups, kids & more
- couples
- One person dresses as a classic yellow Noob avatar, and the other dresses as a Guest avatar with a black cap.
- group
- Have a group dress as different iconic Roblox game characters, such as a Piggy character, a Brookhaven citizen, and a classic Noob.
- kids
- A lightweight, printed Roblox jumpsuit with a molded plastic half-mask is the most comfortable option for trick-or-treating.
- Plus size
- The DIY cardboard box method is highly customizable; simply select a larger shipping box size for a comfortable fit.
Tips
- Ensure the eye holes in the cardboard mask are wide enough for safe peripheral vision, especially when walking outdoors at night.
- If the cardboard torso box is too heavy, line the inner shoulder area with foam sponges or bubble wrap for cushioning.
- Keep the leg movements free by ensuring the torso box ends above your hips so you can sit down easily.
- Bring a small shoulder bag or backpack to carry candy, as the blocky foam hands make it hard to grip small items.
