Professor Layton isn't real. Specifically, the Professor Layton who Tweets riddles and puzzles as @TopHatProfessor. For weeks, he posted totally in character, offering riddles like the ones in the DS games and interacting with other Twitter accounts representing Luke and other Professor Layton series characters.
The account was the work of Roger DiLuigi, a college student and game journalist who just wanted to promote Professor Layton and the Diabolical Box, which Nintendo revealed at E3 with minimal fanfare. Crispy Gamer interviewed the man behind the hat about the phenomenon, which now includes a sort of ARG message board. "I figured that if Nintendo wasn't going to make the U.S. release of the second game known," DiLuigi said, "I was going to take matters into my own hands."
Dear Nintendo and Level-5: We've decided to jump into the freebie Layton promotion game, and we've got another puzzle just for you. Unscramble this sentence: "For God's sake, please release the Professor Layton movie in North America." This one's worth one Picarat.
