King Thistle is one of the main characters of the series. He rules over the Little Kingdom alongside his wife, Queen Thistle.
King Thistle is a humble and respectful king, and is always kind to new people. However, normally he is often hungry and grump, when he's not taking the role of a king.
He's sometimes a bit of an airhead, not being aware of what's happening most of the time.
He greatly dislikes his own birthday due to the fact that he's getting older. He gets annoyed whenever someone mentions his birthday, but always gets over it after a celebration is held for him.
