I really wanted to do this one so bad :3

1. Bad apple was produced by Alstroemeria Records. More specifically, Masayoshi Minoshima, who founded Alstroemeria.

2. The song was actually released in one of Alstroemeria's album's called Lovelight.

3. Bad Apple is indeed a remix of the third stage of Lotus Land Story, which is named Bad Apple!! (coincidentally)

4. Bad apple is not Elly's theme, even though she's in the shadow art video. Spirit Battle ~ Perdition Crisis is actually Elly's theme. Just note that bad apple is a stage theme and not a boss theme.

5. The famous shadow art video literally started out as a storyboard from a Nico Nico user before Nico Nico Douga user Anira took that concept and turned it into the 3D shadow art that we know about today.

6. You know that there's gonna be a lot of different Bad Apples.

Like this one:

Sorry triggered people.

7. Another popular bad apple parody is HIKAKIN vs _____. In there, it's a Japanese youtuber named hikakin beatboxing to bad apple while the other person, does whatever he or she does.

Just note that there are A LOT OF THESE PARODIES

in fact, I HAD A HARD TIME CHOOSING WHICH VIDEO TO PUT UP

8. On January 30, 2010, CNN made a report about the bad apple video and thought that the SAME creator did the stop motion one.

WHY CNN WHY

9. In addition, touhou fans have been nicknaming it "Cirno News Network", which actually fits the title of the video.

10. With popular songs, there always have to be a dance version of it.

These guys were the first.

When a DANCE version is introduced in a song...

MMD versions are bound to happen. No kidding there's like ten BILLION OF THEM

11. I almost forgot the characters that appear in the shadow art video. (in order)

1. Reimu

2. Marisa

3. Patchouli

4. Remilia

5. Sakuya (I remember a video where someone saw Rumia, but I don't.)

6. Flandre

7. Youmu

8. Yuyuko

9. Komachi

10. Shiki Eiki (I don't say Eiki Shiki)

11. Mokou

12. Keine (plus her HOOKATOOKA form)

13. Eirin

14. Kaguya

15. Prismriver sisters

16. Chen

17. Ran

18. Tewi

19. Reisen

20. Momiji

21. Sanae

22. Kanako

23. Suwako

24. Yukari

25. Tenshi

26. Aya

27. Suika

28. Alice

29. Nitori

30. Yuuka

21. Elly

22. PC-98 Reimu

23. PC-98 Marisa

yeah 23 characters. WHERE'S IKU and CIRNO?!?!?! Did I miss Cirno?

12. I forgot one more thing. Many fans won't have a clue who Elly is since she appears in the shadow art. In fact, Bad Apple might be of the reasons why people started to like touhou.

then there are noobs who think that Embodiment of Scarlet Devil is the first game but then 2 minutes later they find about the PC-98 games and realize that Bad Apple is Elly's theme.

oh the horror

Thank god that I'm not one of them.  I watched Illogical Pine's Touhou introduction video before downloading EoSD.
