Panel 2: And they're off to the races. Looks like April is playing along instead of exasperated, though, which is good.
Panel 3: Now, why is she swooping up Robin, when it was Merrie who was daring April to catch her?
Panel 4: Good grief, I'd forgotten that people do that! And does Robin have propeller head too?
Panel 5: Cool. Good thing she's young and strong, though. Anyone remember a really early Calvin Sunday strip? "Her plan backfired, Dad. I'm all wound up, and Mom needs to be put to bed."
ETA: Okay, so the official site goofed: Saturday's strip is up. Comment if you like, but I'm not going to until I can put it in context. Overall, though, it makes me want to kick something. Perhaps a Lynnion.
