Babar's trusted advisor, Cornelius is an old elephant frequently seen in a weird colonial formal soldier's suit, complete with sabre, although really the most active thing you ever see Cornelius do is let the king's children hang a swing on his tusks. In the early books he wore a lovely bowler hat, until Pom ruined it by floating in a pond with it and capsizing. Babar presented him afterwards with a handsome and grandiose two corner hat, kind of like you'd imagine pirates or herman melville characters (the captains, anyhow) wearing.
