Sox is, for the most part, a laid-back monster. He's pretty lazy, and doesn't do much other than eat. For some reason, he usually eats rocks. These rocks apparently help him stay the way he is, but it's not too certain of what he means by that. He doesn't take too kindly to strangers either. Due to how large Sox's tail is, it's very sensitive. Somehow, Sox owns a lot of money as well, and he owns a mansion. Where he got the money from is a mystery.
