This strip is a continuation of the gag of Snoopy's hypersensitivity towards potential sources of treats, but it's also the first strip in which Linus wears his familiar striped shirt, or indeed a shirt of any kind. He's also out of diapers.
It's another strip, too, where Snoopy gets a thought balloon, and one with a thought-tail instead of a word-tail. Schulz still hasn't gotten the convention down entirely though, and in upcoming strips both kinds of tails are seen on Snoopy's thought bubbles.
