Astro is a teal skin toon with a crescent shaped face. He has a star eye on the right side of his face. He wears a dark purple-blue blanket around him. Under the blanket is a black tank top, black shorts, and he has two sets of arms. Two were they are supposed to be and two on his waist, but since he mostly always wears the blanket no one really sees the under stuff. He also were a sleeping cap with the same colors of the blanket. And at the end of the cap is a pom pom that is a lighter version of the color. Astro is somewhat shy but really friendly if you get to know him. He cares for all of his friends and especially you. He likes to hang out with you the most. He loves just having you around him, and every time you were it gave him more and more feelings of more than friendship.
