Stampy appears to have brown hair and wears a yellow/orange hoodie jacket with a cat symbolizing his Minecraft skin on top of it. He has a black leather jacket over his hoodie when he joins the New Ocelots.
Stampy Cat is portrayed to be a nervous and loud individual. He seems to be friendly and willing to help others, but he sometimes lies when under pressure. He was also portrayed to be a prankster and an expert Redstonist, having won the "Tri-Block Championship" three times in a row (Determinant). He is very upset that the small prank he pulled on DanTDM had led to death and murder, but he shows himself to be very forgiving, as even if Jesse apologizes for failing to save everyone, Stampy does not attempt to put blame on her/him.
