Piggley in “Salmon of Knowledge”

[telling Ferny about the Salmon of Knowledge] A long time ago, in the clear blue waters of Lough Derg, there lived a simple salmon. Hanging over his watery home, there was a very special hazelnut. And inside each and every nut on that tree was all the knowledge in the whole world. One day, one of those nuts fell into the loch. And the salmon gobbled it all up, filling him to the gills with everything there is to know about... well... absolutely everything.
