Alien/Male/Toddler
You decide to try out a three-year-old boy. He is quite sturdy, with brown eyes and brown hair. After a little experimentation you make his cock about six centimetres long - maybe a little bigger than your average 3yo but not extraordinary and give him a good pair of testicles in their bag underneath.
Your ship is equipped with a good store of clothes in all sizes, so you find some shorts and a T-shirt. Then some sandals for your feet and sit around to see who comes along. Eventually, you hear voices and a bunch of kids come walking down the lane. There are six of them, all between five and ten years old, all chattering and messing around. You decide to let them go past. Then you spot a little girl, maybe eight or nine, all on her own. She looks sad as she walks along looking down at the ground.
You go over to the gate and climb up on it. "Hello," you say as she walks past.
