Sorry if I am wrong but I remember asking twice for two characters the first time just before I sent my mass pm to everyone and once after saying that I was making two. Since I can't check back on the post though I have no idea what I said exactly. And my pebbles decreased each time I asked. I went from aproximately 142 pebbles to bellow a hundred the first time and then I asked a second time and my pebbles dropped to around 50 which is why I am now at 60 pebbles approximately. If this somehow isn't the case I will repost another post to the pebbles maintance topic to get another character.
