Jack is a giant living Orange Anthropomorphic pumpkin, he has two big holes carved out, that have tiny yellow glowing dots as eyes, and five smaller Hole's acting as a frown beneath the eyes. Jack also has a long sharp giant Chainsaw replacing his left arm, inwhich it activated whenever he wants. Jack also has an Enraged form, where his skin darkens to dark grey, his face turns into that of a angered smiling demon (that also glows yellow), and he's also much faster in this state.
