KEL ASK 022 is a comic and an ask answer published in 2015 on tumblr by Kelly Green.
ANONYMOUS: “You're the Hatbox ghost? As in, you have power over all hat containers wooden and cylindrical? I knew this one dork who could control all sorts of boxes. He was more annoying than scary. Think you could do better?”
In a one-panel comic, the Hatbox Ghost bitterly states that he admits his is not a terribly impressive power.
