Most of the time, Bill Watterson's Calvin and Hobbes was a straightforward comedy, set in equal parts a nondescript American suburb and its protagonist's imagination. While it's got more than its share of memorable lines and genuine wisdom, C&H was rarely out to tug on anyone's heartstrings. There are two exceptions to that rule. One is a full story arc from March 1987, in which Calvin tries to rescue a baby raccoon. The other is a one-shot from late in the comic's run, as one of Watterson's more experimental Sunday strips. Both are quiet meditations on death, as Calvin confronts mortality through encounters with animals.
