Sleepy Subcon is a Purple Time Rift that can be found in Subcon Forest. It can be located in the center if the giant smashed hourglass. It appears when the third relic is created.
- In a hidden area below the second-to-last stage, you can find a book titled "Proof of Ethical Consumption Under Capitalism". The character notes that all the pages are empty.
- Several Light Plants can be seen in the tubes in the second-to-last stage, the only time these enemies appear in the game as they were cut from the rest of it.
