I spoke too soon regarding the spelling of "coconut." Actually, it's possible this is the first time Schulz called it "cocoanut," and I misremembered. I sometimes scout ahead a few months so I know what's coming up, and I might be remembering this odd spelling from that.

This is the first strip in which Linus holds a blanket, and the first one in which we're told he does it for security-related purposes, although the explicit term "security blanket" isn't in use yet.
On the art of extracting comfort from flannel. Lucy isn't really opposed to it at this point -- in fact, I think you can probably find several strips in which Lucy is anti- and pro-blanket. Their grandmother, however, is less divided about it.
Snoopy keeps one part of his brain awake at all time to watch for food opportunities. It's like a processor devoted to background tasks.
We get the serif-Z representing sleep here again.
We've seen versions of this strip before. An early strip had them playing hide-and-seek, and the width of Charlie Brown's head gave him away.
