Items and chests are randomied, with exceptions listed below. The rod of seasons is split into four items, each of which will give you one season and the rod itself (if you don’t already have it). There is one flute in the game for a random animal companion, and it’s identified and usable as soon as you get it. Subrosian dancing and Ricky do not give flutes as they normally would.
Seed trees and default seasons for each area are also shuffled, and the satchel and slingshot will start with the type of seeds on the tree in Horon Village. The Natzu region matches whichever animal companion the randomized flute calls.
