1) First-Aid Kit (Better safe than sorry.)
2) Lantern (Need to be able to see at night.)
3) Water Pot (Need to stay hydrated, and it's reuseable.)
4) Snack Machine (Have to eat. Can also be used as a barricade, or shoved over.)
5) Candy Jar (If Halloween in AC has taught me anything, it's that the monsters' wrath can be assuaged by sweets. Worth a shot, especially since I'd prefer to avoid violence in the first place.)
6) Golden Axe (Can be used for protection or to chop wood.)
7) Hylian Shield (Defense is important)
8) Bill Blaster (Long-distance weapon with seemingly infinite ammunition.)
9) Bomb (There are a variety of possible uses for this.)
10) Triple Red Shells (Hones in on the target and can delay them.)
Didn't go with a backpack since I figured it would be Animal Crossing logic and I just store all this stuff in seemingly another dimension in my pockets. This was fun.
