The Canyon Tyrannosaurus Rex is part of the Jurassic Park III Camo-X-Treme line. This was a toy line of JP3 dinosaurs repainted in remarkable nature inspired colours.
The color scheme are somewhat inspired by a milk snake with the red, black and grey tones.
The sound effects are the same as the original JP3 Rex so nothing new there.
The Canyon T-Rex features in my opinion the most interesting paint job of all the repaints in that line, therefore making it my favourite Camo-X-Treme by far.
