Morning 002
Hour 1: VII.X.24 -> VII.W.26 (small hardcase cooler - empty)
Hour 2: VII.W.26 -> VII.W.27 (large worm)
Hour 3: VII.W.27 -> VII.V.27
Hour 4: VII.V.27 -> VII.U.28 (large worm)
Hour 5: VII.U.28 -> VII.T.29
Hour 6: VII.T.29 -> VII.S.29 (small snake - doesn't look venomous)
Hour 7: VII.S.29 -> VII.R.29 (threadbare t-shirt - mostly in one piece and huge)
Hour 8: VII.R.29 -> VII.Q.29 (cleaned animal pelt - has bristly brown fur, like a boar, and looks like it's gone through some minor treating processes to preserve it)

Day 002
Hour 1: VII.Q.29 -> VII.P.29 (medium insect - a dragonfly)

The group reaches the mountain foothills at this point, which also coincides with the river becoming a lot thinner, shallower, and easier-looking to cross.

Hour 2: VII.P.29 -> VII.P.30 (medium insect - a beetle with a shiny shell)
Hour 3: VII.P.30 -> VII.O.30 (large worm)
Hour 4: VII.O.30 -> VII.N.30 (carved wooden bowl)
Hour 5: VII.N.30 -> VII.M.30 (medium insect - some kind of grub)
Hour 6: VII.M.30 -> VII.L.30 (large bug - a moth with wide, brown wings and a round body)
Hour 7: VII.L.30 -> VII.K.30 (rusted metal plate)

Don't they say that the fish bite more at sunrise and dusk? Maybe that's what Kokichi was anticipating all along - just before sunset, the group comes across a stretch of river (now more of a vigorous mountain stream) that is absolutely writhing with fish. They might not even need the fishing rod to get a good haul.

Hour 8: VII.K.30 (broken chunk of solar panel cell)

As Kokichi is poking around the area, he'll hear the sound of a drone moving somewhere to the north, moving in an indeterminant direction before the noise fades.

It's now the start of Night 002.
