Definition of PIED PIPER. 1. : one that offers strong but delusive enticement.
Pied is a very common pattern. The pied mutation causes areas of white/yellow to fall where there would normally not be any. Like a piebald horse has patches of colored areas and white areas, a pied tiel is the same that it has patches of normally colored and patterned areas, and other areas are a solid yellow/white.
