Cheerful Mister H.B. Cadmium, Walking Softly to the Store
They call Mr. Cadmium the "dull pencil", and why? Because there's no point to him? Ha, no - it's not that. He tends to squeak as he walks and his footmarks are rather smudgy.
His mother calls him "son" for similar reasons, though she calls most people son (save her daughter Bella, whom she refers to as "her sister's son, John L. Titanium").
Young H.B. is pictured below taking his feathers to the local shop to have them oiled and re-calibrated. They are somewhat of a family heirloom, having been plucked from an old pillow they found in a skip near Colchester.
