The Chiyo Chan Colab

The Chiyo Chan Colab (misspelling of Collab) is a spam flash created on Newgrounds, with some hidden screamers, by "FatBadger" and "Brick-Toppp".

For the most part, it's just a flurry of poorly made references to Azumanga Daioh character Chiyo Mihama; some with "earrape", others with crude jokes, etc. However, the fourth option contains a screamer. Once selected, it displays an image with the text "the real-life Chiyo-Chan", then slowly pans to a picture of a girl cosplaying as Chiyo-Chan. Suddenly after, it switches to a black-and-white flashing drawing of an angry face, over a distorted, pitch-shifted and fast-paced looping scream. This is followed by TV static; another, much more distorted, electronic-sounding scream plays over the current scream, and the words "CHIYO CHAN IS FOR FAGGOTS!!!!!" appear. This continuously loops until you go back to the main menu.

Two sequels were made to this "collab", and also contain screamers. The third option in this collab also contains "earrape", which may scare headphone users.
