Extra-galactic alien (Men in Black)

This extremely large alien only appears in the final scene of Men in Black. When the camera zooms out it is shown playing with some marbles, which have what appear to be galaxies within them; one in particular being the Milky Way. The alien, which has a greenish gelatinous appearance and four digits on each hand, is seen playing with some of the marbles before packing them on a bag.
