farming equipment (in a crate so it's 1 item lol includes tough seeds tools and a farmers almanac to help me start) a sword to be a self-taught swordsman(many free hours) and since i'm trapped the girl that i have a crush on to not be lonely (relationship that isn't all about sex you perverts that read this but done on occasion)
I would bring a teleporter, an endless supply of coke zero and an endless supply of food.
What I would do is just play around, drink and eat untill i wanted to go home or get water. then i would teleport home and if i only wanted water, i'd grab that but otherwise id stay home.
