Heres this baby, It took about 6 hours to get the render/pic. The "story" behind this one:
The Mothership(the big bubble-like ball)
can change the outside color, to blend in with its background. The Mothership also can go more translucent, like the middle pic^, so you can see more inside the ship. Theres a small mouth-like opening, where the Babyships can enter, and leave.
