Did the bamboo boxcar fall apart too? I mean, even with all the resources available on this island, and all the building they've done, Kitteh's still in a hammock, and poor little Pip's still on the ground?
Kitteh likes his hammock. Pip always sleeps on the ground, except when he's in the bindl being carried.They don't seem to mind most weather, either. Still, shade might be nice; maybe that's when they take refuge in the boxcar.
