Kevin's part of my many caches. When I think of them as alive, I almost can see them kinda trailing along behind me, keeping things going in a manner not quite what I originally had in mind although often more funny.
Kevin is kinda small, and yellow, which is good because if I'd painted him purple, I don't think you'd wanna be close to him.
Medium/large pill bottle means the log is easy to spot, the log is big enough to be easy to remove, and the space is filled enough not to be able to handle much in the way of tradables.
