This is it, the trophy of the century. One that will stand out in your collection for all eternity.
To get this trophy early, all you need to do after starting the game is to go left out of your room and enter the bathroom. Sit on the toilet and tap that
button until you create this item of doom. You can also do this at any toilet at any point in the game. Afterward, you'll have to go through the tutorial battles before you can actually use it. Once you get to an actual battle after the tutorial section, just go to your consumables and select the item in question. You'll throw it, they'll vomit, and you'll unlock this stinky trophy.
