When accessing the site, the user is shown with 3 images, with names in order: "Cacadanslanus", "Pumba.swf", "trex.swf", When visiting the cacadanslanus part, the page presents a background of a red wall consisting of a text stating "KEBABFRITES SCREAMERS" which is written at the top, and there is a big rectangular box, where the screamer itself is located, the flash is required to show the file, however, when the fiash is allowed, will show a GIF of a woman from Paranormal Files 2, along with "mechanical" scream, zooming in and out.
At the Pumba.swf part, when the flash is turned on, the site will show a zooming close-up of Pumbaa from The Lion King along with loud pig squealing sounds, The nature of the screamer may have been created as a joke, but it comes across as startling to unsuspecting users, the flash animation was popularized by the French forum website jeuxvideo.com.
The last one, called "trex.swf", where it shows a picture of a dinosaur, accompanied by a mechanical animal roar.
