||Summary: After an oil spill on a
nearby Sunnydale beach, Willow discovers a selkie; that
is, a girl that can turn into a seal with her sealskin.
The selkie, dubbed Ariel by the gang, cannot return to
the ocean because her sealskin was damaged by the oil
spill. Willow's trying to find a spell to clean it. At
the same time, mermaid-like creatures called merrows have
come ashore in search of food and the vampire population
gets territorial and try to kill the merrows. Buffy and
the gang get stuck in the middle of a turf war while
trying to save Ariel.
