Noelshack.comm.free.fr is a screamer webpage created by a french user kebabfrites in 2013.
Upon visiting resulted in a selection of 3 screamers, including Pumba.swf, Cacadanslanus, and Trex. Pumba.swf is a SWF file name given to a close-up animation of Pumba, with loud 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.
Cacalandus is an oman from Paranormal Files 2, and the final, trex.swf is a close-up of a T-rex zooming in and out, accompanied by a mechanical animal roar. Noelshack.com.free.fr exists as a mirror of Screamer Cactus. The website intended to lure users who removed the "M" in the original Noelshack.comm.free.fr domain.
NOTE: The following links contain screamers!
