Myth and legend? There is a connection. At the start I stated that the Mineral Connection to the AOTC has Animal and Vegetable subconnections; myth/legend are an Abstract subsubconnection of the Animal subconnection of the Mineral connection to the answer on the card, which is Abstract. I presume that clarifies matters. :)
Begins with P? No.
To do with sounds people make? It can, but need not, be connected to sounds that people make. (Also, sounds people make could be an Abstract subsubconnection of the Animal subconnection blahblahblah.)

(To the extent the last question was prompted by the one occasion of audience enthusiasm, that might indeed be a profitable line of enquiry. Or you might want to pursue one or more of the A,V,M connections.)
