At first it might seem ingenious: "Hey, I'll distract them with this cute sheep and then rip their guts out." But functionally, it's mess. Have you ever tried to keep one of those things tied? The killer would always be having to take a "time-out" to re-tie his or her mask. Too much trouble. Plus, it's kind of dated. SARS just isn't the scare it once was.
This one didn't make it deep into testing for obvious reasons.
Kind of scary in a "honey, is that you?" kind of way. The real benefit of this mask is that despite that the killer is probably an undead rotting corpse, his or her skin will maintain its youthful glow.
I have to admit that I'm a bit surprised this one didn't go deep in the mask selection process. The irony associated with it is just too good. The killer could ask the victim to come and pet the kitty and then when they get close, he or she kills them.
Not necessarily a bad mask, but it's far too expensive to maintain. This thing is some sort of artifact. The costs associated with making sure that the wood doesn't rot and the paint doesn't chip would be too much. In close combat, the killer would be too worried about hurting the mask and not worried enough about hurting the victim.
