Roblox is an online gaming platform that allows users to create their own games as well as play those made by other users.  A Roblox noob's avatar is often depicted as a generic, square-shaped humanoid.  While there is some personalization available, a stereotypical noob will be yellow with a simple happy face, blue shirt, and green pants.  You can use a black fabric marker to create the smiley face on a yellow zentai suit, and then layer clothes over it to recreate the avatar's look to your specifications.
