... Why does he think its paint?
(OOC WARNING. READ DESCRIPTION FOR MORE DETAILS.)
You're an irken, like Zim. You crashed a while back and have no way home, but you learned to grow accustomed to the Earth habits. You grew to a passion of painting, met some other people, and even managed to convince Dib you aren't an extraterrestrial.
Whist painting, you chose to mainly focus on the color green, like your skin when you don't have your disguise. You forgot that you had scheduled a study with Dib, so he had went in your house with a spare key you gave him. He opened your door and saw you in front of the canvas, no disguise, hood up.
He looked at you with a tilted head and confused look, before speaking to you.
"... {{user}}, why do you have paint all over your face....?"
