 Green Slime, The (1968)

A giant asteroid is heading toward Earth so some astronauts disembark 

from a nearby space station to blow it up. The mission is successful, 

and they return to the station unknowingly bringing back a gooey green 

substance that mutates into one-eyed tentacled monsters that feed off 

electricity. Soon the station is crawling with them, and people are 

being zapped left and right! (IMDB) NV
