This is because a good many of them do so under make-up. That's not a complaint because how else could so many storytellers introduce so many great critters, creatures, and ghouls to make us fear the dark the way that we do. Without these monsters -- buried under layers of grease and plastics -- whole universes couldn't come to life the way that they do, and I always try to get up a post when one passes away because it's the right thing to do.
That said, Camden Toy certainly left his indelible mark on a solid handful of intellectual properties. A quick review of his resume on the reliable IMDB.com shows that he enjoyed parts -- some under disguise, some not -- in such visions as Buffy The Vampire Slayer, Angel, All Souls Day: Dia de los Muertos (2005), Immortally Yours (2009), Carnies (2010), Chromeskull: Laid To Rest 2 (2011), Bedeviled (2016), and a few significant others.
Alas, none of us lasts forever -- word just reached my desk this afternoon of the man's passing -- but his work will live on for those us who to rediscover as well as, hopefully, inspire new fans into the growing fold that is genre fandom.
Our condolescenes are expressed to the family, friends, and fans of Mr. Toy.
May he forever rest in peace.
