It's been wrapped in wool, given a serious case of blue balls and donned a pair of swish black sunnies for SpyFest.
But, it's latest makeover has sent Goulburn's Woolly icon well and truly viral.
The Big Merino's eyes are now green.
Transformed to promote The Goulburn Group's Connects Festival on Sunday November 15, the makeover attracted significant online attention on Monday morning.
While it's intention was to encourage passersby to "make the switch" to green energy, the image originally published in the Goulburn Post has been described as something similar to "a mutant radioactive sheep".
