Caveat emptor, Marnie, pondslimes are really an acquired taste. Some might find them quite unpalatable as the copper-yellow-gold coloration (au naturel) might clash with skin or hair colouring. The experts have said that pondslimes have always been around, just bleached into oblivion, as consumers tend to give such colour a wide berth in the past. Till of course our very forward-looking Sarah at Kojima and Fuji at Pacific saved them from their bleach bath destiny and these days, consumers are alert to their existence.
I personally find white pondslimes too harsh for my sallow Asian skin but I adore mauve pondslimes (purple-copper-gold and even green hues).
