I can imagine these critters, "Worst contact of the First Kind" every trip...
"Woah! So this world is inhabited...? But, hey it's just these primitive savages... Scanners say mobile PLANT life!? Hey! This'll be cool! Space Hippies! We'll buy the planet for a handful of beads, learn some cool new drugs that'll make a fortune for a few years before the law bans it, then we'll sell and market their culture even the 'protest' music against us 'exploiting' them!!!"
"Hokay! Let's dress like hippies too, no weapons, get the box of shiny stuff, the sucker the native kits..."
Walks towards the village,
Through translate "Greetings, fellow creatures of the universe! We come to share the message of universal peace...!"
