What's 9 + 10?
What's 9 + 10? is the true final floor of Rodney's Tunnel, accessed after defeating Rodney. It is not a part of any major area and is made up of assets from previous parts of the game. It recycles the dark corrupted sky of Between Ricky Hills and the tileset of Signature Walls. It is only inhabited by an incendiary pig named THANKS FOR PLAYING -Kjolt. This area serves as a final thank you message to the few people who played and finished the game.

Trivia
- The music that plays here, "Party Shell" is a Kjolt original from September 12, 2021.
- The floor's name refers to an iconic meme where a young boy is asked "What's nine plus ten?", to which he responds "Twenty-one". This also happens to be the 21st floor of the game.
