March 7Snoopy's candy detecting powers at work again. We've already established that Snoopy has a much longer detection range than this. Note: both of them are probably inside here.
March 8I've said it multiple times before but it really should be driven home: chocolate is toxic to dogs. If we can bring ourselves to overlook that little thing, we can notice that chocolate creams are the default "good" candy of Peanuts. Come back in two days to find out the default "bad" candy.
I seem to remember Snoopy doing the "mmmm" thing later on, and it annoying people. I don't have a clear recollection of it though, it could be something else.
March 9Linus is doing his googy face again. It still looks funny to me. I suppose this is the expression he makes when he sucks his thumb, but without his thumb in the way to obscure it.
March 10Charlie Brown hates coconut. Apparently, so does Snoopy. (Their opinions on the issue closely mirror my own.) In both this strip and March 8, the girl is used entirely as an observer, someone to which Charlie Brown can talk without seeming like he's talking to himself, or directly to the reader.
March 11Lucy is at that magical time where she can say something that looks like pure glurge, but then turn it around 180 degrees in the last panel. Charlie Brown exists in this strip to tip off the reader's reaction. The second panel could be taken straight (it's a lesser reading, but possible), so Schulz put him in there to let us know it's supposed to seem sappy, and so we'll be able to see how loud Lucy is being in the last panel.
That disgusted look on his face in the second panel is not a standard Peanuts expression, I notice.
March 12Somersault! Aaugh! You know, I think this might be Peanuts' very first "Aaugh!"
Bugs are not a part of the balance of Charlie Brown's back.
