It stirred.
It sensed warmth nearby. Movement. It immediately began processing information.
It lived for one purpose. To find a strong, compatable host for the embryo within it. The embryo seeder was well endowed to do just that.
The seeder wasn't alive in the same way that the Queen above and the embryo within it were alive. Rather, it was more of a para-life form... a semi-extension of the embryo itself. It had its own mobility system, its own respiratory system, all adapted to perform its function with supreme efficiency. The seeder was almost like a surrogate mother in and of itself, albeit a short term one. It acted as a mobile environmental incubator, protector, and matchmaker all in one. After all, while many life forms made excellent hosts, there were some basic requirements which needed to be matched; the seeder assured these matches were met before expelling the embryo within a host. This usually wasn't a problem; one of the strengths of the Xenomorph in all of its forms was its adaptability to a wide range of hosts and environments. In fact, it was remarkably adaptable - beyond that of most other species at its advanced developmental level.
The seeder used its appendages to crack the top of the leathery pouch open it had developed in. Four flaps parted, exposing the outside world from above. The seeder stretched its spidery digits. It crawled out to balance itself on the edge of the leathery pouch that had been its whole world until now.
It immediately assessed its surroundings.
A shrieking sound echoed through this place; the seeder homed in on its source and found what had triggered its activation within the egg. A viable host. It seemed nature had built the hosts with their own locators. If the seeder were capable of higher function, it would have approved of the practicality of this.
The seeder leapt from its perch, landing on the source of the sound. It seemed the host's design was as efficient as the seeder's; the sound eminated from the very orifice into which the embryo would be implanted. The seeder knew this instinctively, and shoved its phallic embryo insertion tube into the opening, penetrating deep inside the warm body of the host.
The host gagged, but before it started convulsing the seeder released a sedative hormone into the host's lungs, where it would be regulated into the bloodstream. Then it began feeding a supply of local gasses to the host so that it would continue to function. The survival of the host was mandatory, in order to assure the proper development of the fetus.
The host's brain continued to regulate the boilogical functions necessary for life. It was time; the seeder began the process of depositing the embryo into the host.
Amidst the darkness and sound of dripping water, a second egg opened.
