Vocaloid Cameos in Zoku Sayonara Zetsubou Sensei

I finally watched the ending of it today, and I missed a few of the cameos. When I went to look it up on youtube, I couldn’t find it, so I tried to make one myself. Appearances: Red and Blue Rin and Len - 1st part Green Kaito - 1st part Blonde Meiko - 1st part Miku Hatsune - 2nd and 3rd part
