Old Man McGucket points out that cryptograms can be found throughout the series. He says that he can read them but doesn't understand the meaning behind them. He has tried using several languages in an attempt to translate the cryptograms, including some form of western Manotaur script and "Possum Sanskrit," but that he still can't make sense of what it means. He concludes by saying that he doubts this mystery will ever be solved and that it's time for him to have his hootenanny, and then proceeds to have the said hootenanny.
