Doctor Guam, or simply Doc Guam is the oldest character in Bone so far. In Tall Tales he was seemingly elderly, and in Quest for the Spark 2 he is still alive! This may prove that Stinky and Smelly were present when Big Johnson Bone visited The Valley. Doc Guam is a, as his name suggests, doctor. In Tall Tales he diagonises Queen Maud's son Tyson with Fire Pixies to Music Pixies in his stomach, which the severity depends on the quality of the music. He is mentioned centuries later in Quest for the Spark 2, where King Agak remebers yelling is not good for his gizzard, advice that Doc Guam gave him.
