- There is a bug that occurs in the Dreamcast version if you exit and re-enter the level. When approaching the path to the Door to Nowhere (usually when all Tokens have been collected), an invisible force will force your fighter slowly off the cliff, fluffing them. The only way to get through it is to make a path straight backwards as far as you can without falling off. When the bug lasts long enough without you falling off the cliff, it will eventually stop, and you will regain control of yourself.
- If one were to re-enter the level after completing it, turning around at the starting point and looking into the distance, black smoke can be seen. This is the same black smoke that emits from the tanks in Roofus' nightmare when they are immobilized. If the player jumps towards the smoke, one could actually make the level area pop in to view. With Tweek, the player can glide, getting a closer view of this phenomenon for a longer period of time. However, you cannot enter the area via this way and you will eventually be fluffed. Should you decide to glide around, you will also be able to see the other Nightmares too.
