- While the idea of the Ass-Blasters can be rather silly, the fact that these creatures eventually come to possess the power of flight is actually rather disturbing.
- In addition, the Ass-Blasters actually have a somewhat menacing appearance. They look like slimmed down Shriekers with all-black faces.
- The deaths of the three federal agents, due to the fact that two of them die offscreen and the remaining one is clearly traumatized.
- Burt getting eaten by a Graboid. Thank God he survived anyway.
- Miguel's death. An Ass-Blaster flies into him, sending him careening off a cliff to his death. We don't see the impact, but we do see just enough of his remains, while the main characters reactions do the rest.
