As her garden has a long-established pond which attracts several frogs, she suffers regular shocks. Despite the efforts of her husband to keep the pond clear of both spawn and frogs, the air is often rent by a scream as another marauding amphibian pops up unannounced. Frogs, like many creatures, can be surprisingly single-minded come the mating season. A living, writhing 'ball' of frogs stacked one upon the other underwater are often so preoccupied by their Roman orgy that onlookers can get amazingly close, a fact which presents a convenient smorgasbord opportunity to any hungry heron or pike. Goldfish are sometimes even killed by amorous male frogs who fail to find a mate and end up clamping their forelegs around the fish's gills, suffocating the poor wretch as they try to get their wicked way.
Nature can be cruel.
