He likes this MOO, his favorite color is green, his favorite animal is anything with long ears which jumps at high speeds (Rabbit, Hare, Kangaroo), he likes anime. He tries to stay happy even when it is not normal, and tries to let go of all his emotions at once when they are getting in the way. If you ask him nicely, he'll do his best to help you with anything, MOO-related or not, and he might try even if you don't want him to. However, people who are constantly trying to boast how great they are at something is irritating, and quite easy to crush. Don't let your self-confidence overcome you. Show him something you did, then let him draw his own conclusions. (Sorry, bit of a rant. This doesn't happen often, but it's really irritating when it does.) Remember, smile smile! :D
