Ferocity Dinosaur is the name given to a series of sound-activated, singing Dinosaur plaques from Disga Toys, aka Tech Seeking, that appear to be from around 2004. Apparently, they are knockoffs of the dinosaur plaques by How Shan Development.
Their boxes feature an image of a T-Rex which has been used on the back of VHSs of "Jurassic Park: The Lost World", and the logo rips off the "Reign of the Dinosaur" logo featured on the boxes of the 1999 version of WowWee's Dinotronics RC dinosaurs.
A total of seven versions appear to have been documented, including two prototypes. I don't know what type of dinosaur the yellow one is supposed to be.
Each dinosaur's plaque is labelled with "DINOS AURS" (with 'N' backwards), instead of the name of the species. Also, "Gojiorasaurus" is the official name for one of the dinosaurs.
They move their head in a circular motion, roar, and sing "Put Me Back In the Water" and "Under the Water". Also, their eyes have lights that flash as the dinosaur moves.
