Margoyles take advantage of their slightly higher intelligence to lead gargoyle groups. According to this article, margoyles can live to be about 300 years old. The margoyle hatchlings join together as a pack, hunting larger prey excepting those runts cannibalized by their clutch-mates. Newborn margoyles are two feet tall at birth, and emerge ready to eat anything that moves. Margoyle eggs start out larger than gargoyle eggs, and absorb more minerals during their growth than the common gargoyle, ending with eggs two feet long and 18 inches in diameter. The article Marlgoyles & Monster Manual II, Polyhedron #22 (1985), by Gary Gygax, detailed the margoyle's equivalent of an alternate gargoyle life cycle that had been detailed in another article, Why gargoyles don't have Wings but should, Polyhedron #21 (1984).
