Janko Goaston - or Janko for short - is a character owned by the user JankoGoo.

Janko is a male colorblind character, that can't see any spectrum of colors. Instead, he only sees in greyscales. He's also unable to see things or even other characters, that didn't move over an extended period of time, usually 10 seconds.

Janko has two forms: A goo-wolf and a wolf form.

According to DragonSnow4 and JankoGoo, this character is based on Puro from the game "Changed". The character was approved by DragonSnow4 and is therefore officially owned by JankoGoo because of this.

JankoGoo prefers him not to be called a "Puro", because quote:
"Puro is a dark-latex creature. Janko is not. He's goo-wolf or a wolf. But not a latex-wolf."
