- This series gives a twist to the normal FOP feeling: instead of being happy and colorful, this series is more concentrated on drama, suspense and plot twists.
- The Season 2 theme song was originally meant to be Du Hast by Rammstein, but because Total Drama World Tour:The Fairly OddParents Version used the song first, this was later scrapped and changed to Du riechst so gut (1998 version), another song by Rammstein.
- The Give Me Your Soul song was originally meant to be Pussy by Rammstein, but this was scrapped because the song was sexually explicit. Even the instrumental version was scrapped because the title gave already a vague idea of the song's argument (you can watch the song's video here).
- Rammstein songs are used a lot in this spin-off, because Giganicky, the creator of this spin-off, says: "The songs are dark and powerful, thus they fit for the dark and dramatic feeling of the series".
