The notes on the map to One-Eyed Willy's treasure are all in Spanish. 

When the Goonies get to the organ trap/puzzle, Mouth reads the instructions:

> 
> To move on, play the tune......as each note is said. If you make too many mistakes... ...ye will surely be...
> 
> 
> Be what?
> 
> 
> ...muerto.
> 
> 
> What is that? Come on.
> 
> 
> Dead.
> 
> 
> 

But the Spanish translation of the instructions as read by Mouth would have been

> 
> Para seguir adelante, toca la melodía...cuándo toque cada nota. Si cometes demasiados errores...seguramente estarás muerto
> 
> 
> 

Do any of the supplemental materials explain why the English translation mysteriously rhymes when it was originally written in Spanish?
