Samo is one of the Cappies in Cappy Town. He runs the local bar where he sells drinks and hears the villager's problems, which he then tells Mabel about. He was one of the few who knew she wasn't a true psychic, not that he minded. They both care about each other, though Samo tends to get a bit sappy.
He has a more calm voice in the Japanese version, whereas, in the English version, it sounds rather goofy.
In the English version, he speaks with an Irish accent, which is ironic since he sells drinks.
