I found it interesting that One Piece crew just revealed it's 'real' name via OP Movie Stampede.. they called it:
And I was freaked out because how ridiculous the name of this island actually is. And also it's implications. Like, Laughtale is only a made up story. Just a jokes.
Like.. wow. my 20 years One piece knowledge is a lie?
But then I remembered. The eternal logpose in the movie is possibly a fake. Because the real logpose that records the route to Raftel has been thrown by Roger to the sea. So that is very possible that Laughtale is not a real name.. but a homophone name to distract us? It's also possible that Raftel is actually Raft-tale? Hmm...I just cannot accept the idea of Raftel being Laughtale. And Reverie being Levelly? Like..hello?
