>>1131457I would have made one of those crabs my Wilson. I would feel less weird talking to a crab and I could watch him eat things for entertainment.
As for what I'd do differently: he only catches fish by spearing them, he could've built pic related around the island and had a passive source of fish. Then he could use the leather from the fish to sew clothing using sinew from the fish or plant fiber as thread and a bone or wooden needle.
There were crabs on the island and he could've started a crab farm in the 4 years he was there.
Early on he had a shoelace from the ice skates. He should've tied the lace to a curved stick and made a fire bow. He would have had a much easier time making fire with one. Even the lens from the flashlight would've started fires during the daytime.
I would keep coconut halves scattered about to hold rainwater. His inflatable boat could've held a lot of rain and he wouldn't even need to worry about water for a week if he filled it on the first night.
