Synopsis by Hal Erickson
Knocked unconscious while swimming, Gabrielle (Renee O'Connor) awakens to find herself in a watery world populated by mermen and mermaids. She herself has grown fins in place of her legs, and has now assumed the identity of Crustacea, the wife of merman Hagar (Ted Raimi) and the mother of three bratty piscatorial youngsters. Meanwhile, a pair of scaly villainesses who closely resemble Gabrielle's earthly nemeses Aphrodite and Discord hatch a plot against her. This anachronism-packed comic episode may remind the viewer of such theatrical features as Splash and Overboard.
