Avery Arable is the elder brother of Fern. Like Templeton, he is a source of comic relief. If Avery were our brother, we might run away from home—or at least hide our valuable possessions. He's the most rambunctious kid you'll ever encounter. Since he's Fern's older brother (he's ten, and she's eight), you might think he'd be the older and wiser type. You know, the kind of brother who would make fun of Fern for acting so immature. But nope, he's as wild and crazy as any kid out there.
