Blipped the blip hunters!

In this world there are blips and blip hunters.

Blip Hunters
They search for and record the little critters called blips, once thought to be mythical creatures that only children can see. These 4 hunters move around with a video camera and a large antenna specially made to detect the sound that blips make. These hunters are skilled in identifying the places where blips hide, picking out blips trying to blend into their surroundings making their little blip sounds.

I have learned something about these 4 in particular. They are actually aliens.

The one holding the antenna is their leader. THIS is where they landed in their ship. The second one from the left chose this lamp post to mark their departure coordinates. The one with the eyes pilots their ship. The last one is their clean up guy. He makes sure they don't leave evidence of their alien existence. They tend to shed.
