Arven is also able to be inflated like a balloon to just about any size, even if he isn't usually the one in control of it. Arven is fiercely loyal to his friends, and while he may not get the best grades in school he's an extremely talented chef. Arven struggles with some abandonment issues, and may seem a little possessive of his friends at times.
