>>32664423>Food supplyTropius is the to-go choice, as fruit is a good choice of nutrients to be stuck with. If tropius isn't an option because it can fly away, then Ribombee for the pollen puffs. In any case, if Tropius is allowed, it is a very efficient choice: grows food, it itself feeds on sunlight which there's plenty on a fucking tropical island, and if it needs fresh water it can use the one provided by my following mon of choice.

>Fresh water supplyLiterally any water type, but if you can't swim or fly away with it, then pyukumuku. It's pretty much moveless, needs no care other than feeding it at least once a day, but in return it can purify stuff and I'd assume that means it could make salt water drinkable, as well as produce fresh water from zero because its a pokemon and pokemon are magic fucks. Having a hand inside of it also comes in handy if I need assistence in building, manipulating or moving stuff.

>OtherConsidering tropius is already big enough to give me a sort of shed with its palmtree wings in case it rains and that this is (I assume) a tropical island and there's no need to worry about dying from cold, then I would prioritize a mon that could provide medical aid for the 4 of us. Literally any pink mon would do, but I would pick blissey because its bulk is so massive I'm sure it can last 100 days, it could feed on tropius' fruit and drink pyukumuku's water, and in return it can heal any one of us with softboiled. Aromatherapy for illness or stress. Its egg is a source of protein if I need it.
