Syfy

Morphing Clock (1993)
ID: TBA

FX/SFX: Live-action for the grandfather clock, and possibly CGI for the monster.

Music/Sounds: The sounds of the clock accompanied by a creepy theme, followed by a voice saying "You are watching the Sci-Fi Channel" and a woman's scream.

Availability: Extinct.

Editor's Note: None.

Alien Plants (2000s?)
ID: These are actually a series of idents that played during subsequent commercial breaks during the same show. They focus on invading, carnivorous alien plants that eat anything that happen to get in their way. For example, one ident shows a bird being eaten and the final ident contains a human hand being eaten.

FX/SFX: CGI animation.

Music/Sounds: TBA

Availability: Extinct.

Editor's Note: The subject matter in these idents can creep some people or at the very least, scare some.

Halloween Week (2015)
ID: Basically it depends on the ID, and it's hard to describe in detail, but here's the concept: Something Halloween-related will appear at the start (cards, a baby doll, a grim reaper, a huge mantis-like bug, etc.) Then, some of these will remain showing briefly, until we cut to a dark background with blue/white cards, the word "HALLOWEEN" in a creepy font with "W E E K" under it and the "O"'s hole filled with black and containing a skull, and a bug walking in the down-right corner. Then the scene flashes to the Syfy logo on a blue card with two other cards on the left and right (both are white), with one containing the skull and one containing a flaming circle. A huge bug (different from the mantis-like one) walks on top of the setting. There are three idents in total.

FX/SFX: Live-action.

Music/Sounds: A bunch of Halloween-related sounds, such as a creepy music-box stinger, droning sounds, and sounds corresponding to the subject matter. The ending of these idents always have a 2-note stinger.

Availability: Extinct. They were only used during October 2015.

Editor's Note: The extremely dark atmosphere, some of the sounds, and the bug at the end (not to mention the effect that it will have on people that are scared of bugs) can terrify many viewers, though these are intentional due to the fact that they were aired on October.
