Mr. Blood
From Pfnetwork
Mr. Blood is a glob of blood with eyes, nose, mouth, and thick black eyebrows. He is Mrs. Bunions boss/sidekick, and appears in many cartoons with her, as well as in the The Mr. Blood and Smarty Pants Show. Since Mr. Blood is made of the latter material, he is impervious to harmful objects or situations, and is possibly immortal. Mr. Blood is extremely grumpy, and hates all holidays, as seeing other people happy drives him insane.
