This fearsome matriarch stalks egg-laying creatures in swamps and wetlands until it finds the perfect time to strike, then takes over their prey's egg-laden nest as if it were their own. D'eggios will lay on top of eggs for days or weeks at a time while tendril-like spikes on their underside piece each egg with microscopic holes and inject their own DNA directly into the egg, resulting in abominable mutant creatures that are more like d'eggios than their original species, although both parts often show through. Although most d'eggio offspring don't live long enough to reproduce, some variants can completely take over an entire biome with the right genetics.
