Eulb is a minor character from the series Dick Figures. He is an alien that's only appearance (so far) is in Planet Asshole, where he visits earth with another alien named Der. Eulb thinks he and Der are funny in their alien way, but they ultimately fail at telling human jokes. Thus, causing Red and Blue to mess with them. Eulb is an alienated version of Blue, considering he is the color Blue and Eulb is Blue spelt backwards. Eulb is presumed to be dead, as he and Der get hit by a meteor while flying away from earth in their spaceship, but after the Dick Figures theme, he says slightly "Ow", meaning that he might be alive. He also has an autotuned voice, just like Der and the Autotuned Bee.
Eulb is bluE backwards since he is the alien-form of Blue.
