River (3)
The second air can is further down the river on the left side of the riverbank. It’s underneath the wooden pathway behind a small wooden pillar.
The third air can can’t be collected right away. You must wait for the event where the train completely stops and the river dries up. Then go down the river and it should be somewhere in the middle.
Outhouse (2)
The second air can requires the red key. In order to get the key you need to go to Ni’s grave with the bucket and dig it up. This will reveal Ni’s hand, which will be holding the key.
Once you have the key, go back to the outhouse and unlock the seat. Lift it up, use your bucket to remove some of the waste, and you’ll find the air can.
Building Two (2)
The first air can is on the other side of the crates. Simply jump on top of the left-most crate and over it you’ll find the air can as well as a message from Ni.
The second air can is on top of the crates. Jump back on to left-most crate and you should be able to walk up onto the next crate, looking on top of the highest crate is where you’ll find the air can.
