The first and second videos are fake. The third one was real.
From The Lost Media Wiki
Some links were found via the third video. http://blog.livedoor.jp/domo44/archives/1190102.html http://ppgcom.blog12.fc2.com/blog-date-200909.html https://plaza.rakuten.co.jp/stimpy/diary/200910020000/ The footage with the dragon and the pill was ACTUALLY the official footage according to me, while the Spongebob and the black colour bars footages were fake.
