Because grandma can use skill books, if she can sleep and recover her brain residual value, she won't be short of food. If you want to restore the brain's residual value, you can find green mushrooms or cacti to roast and eat (never eat them raw). You can't pick green mushrooms in small bags in broad daylight, and you can only pick them at dusk. You can also bring a top hat or garland and wear a beret later.

This hat is more precious because it has a certain chance of exploding when it touches a walrus. Remember to mend it with a sewing kit, and don't burst your hat.

Sleeping bags, tents and arbor can be used to sleep in times of famine. Sleeping bags are disposable (rabbit hair sleeping bags can be used for 3 times) and tents can be used for 5 times. (Sleeping bags and tents can only be used at night and dusk), and the arbor can also be used for 5 times to avoid the heat during the day in summer. But if hounds and BOSS are about to appear, they can't sleep and are surrounded by monsters.
