I figure one more page is in order. My prediction: rain will start, and fall into the box due to angles and wind. The stupid mother tries to intimidate the rain because she thinks she's so goddamn awesome, but obviously fails, so they all melt. Little Marisa crawls from under the cover material, and eats/drinks their remains.
Last 5 to last 2 is the usual scene before Anonymous deliver righteous, but deplored, torture in all the other torture stories.
The large one says this doesn't taste as good as orange juice, it's been spoiled, and the small ones are telling it to shut up. ^^^ They're crying because the cold wind is blowing in. They then tell the mother to hurry and do something about the cold. The sky is making the goro goro sound of impending lightning storm.
I guess they'll see the little marisa having a cover that doesn't sog and steal it but realize it's only big enough for one of them. Either the mother will take it for herself or the small ones will get it and laugh as their mother melts.
