From Screamer Wiki
The melancholy of the 8-headed Mona (八頭身モナーの憂鬱) also known as depressed Mona is a Japanese flash screamer created by unknown user.
The animation starts with a white background with a red text, 八頭身モナーの憂鬱 (The melancholy of the 8-headed Mona) then fade out to a kaomoji cat guy who has a boring expression on his face while saying "Ha... »1-san" then a kaomoji figure of a boy appears while kaomoji cat guy said again "Ha... ha..." "Ha...Haa...Today is a day.... " until then an image of an eerie man's creepy face with cavities on his teeth pops up along with the scream.
