A more useful cardboard box
When you're in the cave area with Meryl, hit her and quickly equip a cardboard box. She'll order a wolf to attack you, but if you're in a box, a wolf will pee on it instead. Now whenever that box is equipped the wolves will no longer attack you.

Easily cross minefields.
If you don't have the mine detector, but want to cross a minefield without having to worry about blowing up, just go up to the area where you believe mines are and crawl across the ground. Not only will you be unharmed, but you will also receive any claymore mines that you crawl over!
