Alistair was a former student of Charles Darwin Middle School. He was a rare central Indian white tiger, and the star attraction of the Zoo most students came from. As a result, he became very pompous. Many of the students and even school staff disliked him as he was so conceited that his arrogance was nauseating... Literally. According to Principal Pixiefrog, when they finally got a chance to ship him off to Greenland, they institutionalized an "Orange-Only" policy (Meaning they will only take orange tiger students) and managed to get Henry to fill Alistair's place so he wouldn't come back.
