Alone is what you think.
Like the other Stomach Dwellers, the Alone Hand lives in the stomach of Dave. In the events of Journey to the Center of the Dave, he met Uma and, after the other stomach dwellers escaped Dave's stomach, said he wanted to be alone with Uma forever. Soon after, Dave ate "everything", and he was crushed by a stack of books, so it is presumed that he is dead. He is portrayed by Buckteeth
