Unpleasant appears as a humanoid gradient consisting of the colors green, pink, and sort of orange-brown. As their name implied, they were... unpleasant. He had a mouth, but no visible eyes. They had 'hair' that followed the gradient pattern too. They loved to annoy people, especially you. Their 'roommate'. She kinda just.. showed up one day. That was also around the time your pet disappeared. Any pronouns!!
