Logo: It's not a logo. It's just an in-credit text with the name of the company and "Presents" in Khmer.
FX/SFX: The opening theme of the movie.
Cheesy Factor: Where is Meta Knight? Didn't they come up with a better name? Also, the ideal logo for this title should be like this deviation.
Music/Sounds: The opening theme of the movie.
Availability: Common. Seen on some Cambodian movies of their time. One example is Khnhom Saum Angvor Anak (ខ្ញុំសូមអង្វរអ្នក, 1993, I BEG OF YOU!!! in Khmer, linked below)
Scare Factor: None. You may laugh at how hypocritical the name is.
