"Don't worry about it."
— Crayon Box, "Who the hell recommended Glowing Heart"

Crayon Box is the main host of OSO. She is aided by her co-hosts Blue Crayon, Green Crayon, Red Crayon, and Yellow Crayon.


She is very charismatic, energetic, uplifting and optimistic. Despite this, she can be angered and even becomes violent when pushed too far or if a rule is broken. This side is more akin to being a harsh schoolmaster rather than just being a pure sadist. She is very loud and usually shouts and people are intimidated by her and don't dare disobey her due to this. She carries around four crayons in her head, each with different personalities. They can sometimes frustrate her.


Crayon Box is a flat, light blue crayon box with slate blue corners on her front. On her top is a flap that can be opened and closed. She may be inspired by packaging for Crayola art products.


Episode 1 - "Who the hell recommended Glowing Heart"

She was first seen on a platform high up in the dome before it lowered down, and welcomed the 32 contestants to Open Source Objects. Guarana asks how the show is "Open Source," and CB tells him not to worry about it.

She proceeds to address herself to the contestants, while also trying to prevent the crayons from interrupting. She leads the contestants to the challenge area, where she introduces the challenge for the episode: after the contestants are tied to helium balloons, they must get down without dying.

Episode 2 - "Your Opinion is Invalid"

Once all the dead contestants are recovered, Crayon Box tells the contestants who were up for elimination to follow her to the elimination area. With the help of Yellow Crayon, she explains how elimination is going to work. She then announces who is safe, but before she can announce who tied in votes, Loren gets up and leaves, much to her surprise. Crayon Box attempts to go after him, but can't convince him to come back.

Black Square was the one who was supposed to be eliminated, so Crayon Box tells him to watch himself in the future. Afterwards, Crayon Box uses a chalkboard to explain the next contest, which angers Yellow Crayon who tells her to use the Crayons to demonstrate instead. She awkwardly stacks Yellow Crayon on top of Green Crayon to explain that the challenge is to stack on top of each other. When everyone is paired up, Crayon Box starts the challenge.

When Inhaler falls off of Vape, Crayon Box makes a bad pun that Corny doesn't understand. The pun apparently had to do with breathing in, as in Vape and Inhaler. She later announces who is up for elimination.

Episode 3 - "The Good, The Bad, and The ********"

Episode 4 - "The Butterfly Effect"


  • Crayon box has a running gag where she tells a bad joke, which are usually bad or confusing.
