Blockhead isn’t human, but he is a male. His head is a sphere with two cartoonish black lines for eyes, and a cartoonish mouth. He is a colorful yellow. He wears a red long sleeved shirt, blue pants, and brown shoes. He’s extremely dimwitted, undereducated and somewhat (though unintentional) destructive (though well-meaning), Blockhead constantly ignores his Conscience (much to the Conscience's irritation). And he’s very hyper active and energetic. He says very random stuff.
