Stray: Where to Find Energy Drinks
You can trade energy drinks for other items in Stray from Azooz, the merchant in Slums.
You can find energy drinks in a vending machine near the Slums. There are two in the lower part of the Slums. One is almost opposite Morusque, which you will need to give the music sheets.
Although you don’t need to collect energy drinks to advance the story, collecting all badges and completing the game is necessary. To collect any trophies or replenish the vending machine, you can use chapter selection after the game is over.
