The Calm-Down Corner is a location that was created for agitated contestants that need to "calm down". It first appeared in Marsh on Mars and has been seen and referenced ever since.
The Calm Down Corner is simply two brown walls adjoined at a right angle, hence the "corner", which appears to be in an open grassy space. Various graffiti marks have been made by those sent to the Calm Down Corner, such a green line, a green squiggle, a black skull and crossbones, a yellow tic-tac-toe board (O's win), and a crudely drawn OJ. Messages have been written on it as well: "TACO WUZ HEAR", "Praise thy Calm-down Corner", "OU (Object Universe) ROCKS", and "PB (Paintbrush) is a (smudge)".
In A Kick in the Right Direction, Paintbrush tries to tell Lightbulb to send Yin-Yang, only for her to send Paintbrush instead. He/She is seen at the end of the episode, sitting in the Corner, still angry. A new graffiti mark has been made since. It says "I'm coming..." in the same pink color and handwriting as the letters that were in Box.
In Let 'Er R.I.P., the Corner is not seen but is again referenced when Paintbrush asks Lightbulb if she's going to send him/her to it again.
- The Calm Down Corner is actually a reference to a real-life occurrence in Adam's life.
- Many references are made in the graffiti written on the wall:
- The skull with crossbones look similar to those that Duncan drew in Total Drama Island.
- "OU ROCKS" is a reference to the object show Object Universe.
- "PB is a (smudge)" may reference the possible answer to Paintbrush's unknown gender.
- "TACO WUZ HEAR" may reference that Taco is still taking refuge on The Island.
- Speculation by fans started when they spotted the pink words "I'm coming..." under the skull and crossbones and thought that was from Bow. However, that was proven wrong, so it's currently unknown if they have importance or not.
- However they did hint things that did/would happen in the future such as:
- A major role for OJ (Everything's A-OJ)
- The first physical reappearances of Bow (Let 'Er R.I.P. now as a ghost) and Taco (first in Everything's A-OJ but was hidden and officially in Rain On Your Charade) in since Journey Through Memory Lane (Part 2).
- The revelance of Paintbrush's gender (not confirmed in any present episode so far, but will be).
