Interesting observation, Smackdab (welcome to the thread, eh). I got a chuckle whenever NOSYYYYYY LINNNNNDA was said. I interpreted the jarring narration as the creatures struggle to control its human host. Heh, William Shatner might be a fellow CDN, but he’s a hack!
In fact, the narrator’s tone made me think of the Edgger-Bug creature from the original (and still the A1 awesome) movie, Men In Black.
