When Kay regains his memories, he and Jay go to the pizzeria, where Laura, hiding and prepared to defend herself from intruders, accidentally smacks Jay in the nose with a pizza tray. However, Jay's nose doesn't bleed, and it doesn't take long for him to recover.
Humans and aliens fight (often with guns) throughout the movie. Several aliens die.
A man grabs a woman from behind, holds a knife to her throat and drags her behind a bush; we then hear gobbling and crunching and the woman emerges from behind the bush with a distended tummy (the woman, who is actually an alien, has apparently eaten the man who attacked her).
Snake-like tendrils slither out of a woman's fingertips in several scenes: Once the tendrils poke into a man/alien's ears and come out his nose and mouth, once she uses them like a whip and slices the "skin" off a man/alien (we see the skin lying on the ground and it looks like a pile of rubber), once she wraps a man in a bundle of tendrils and holds him upside down in the air.
An enormous alien worm crashes through a skylight and another alien emerges from inside the worm, grabs a man and wraps him up in its tendrils (the man bites on the tendrils and another man shoots at them).
We see a ransacked room full of aliens that are torn in half and moaning (they are able, however, to put themselves back together again).
An enormous alien worm with numerous mouths and lots of teeth eats part of a subway train; the people riding the train run and scream in panic.
A man/alien is shot in the head a few times, he spurts green goo and then grows a new head.
A woman/alien wraps many people within her tendrils.
A man picks up a shovel and calls for his mother (it is suggested that he is going to use the shovel to harm her).
A dog is tied up and gagged.
Several planets explode after they are hit by a beam shot from a passing spaceship.
