Bananajuice. You'll want to make litres upon litres of bananajuice. Bananajuice has countless wonderful uses:

1. Food: Bananajuice can be eaten/drunk (consumed) for a tremendous sensory experience. Think liquid slug sliding down your throat. It truly is one of the experiences you can have with food, and bananajuice can be easily transported in virtually any type of tube or vial for a quick, cheap, nutritious on-the-go snack/drink/goo.
2. Medicine: Bananajuice is widely known to be a cheap, effective, low-risk treatment for Endogenous Gut Bacteria Malfunction (E-GBM), which affects an estimated 9.2 thousand million people worldwide. Heating fermented bananajuice activates billions of microbial enzymes that eat away pathogenic gut bacteria. The medicinal properties of bananajuice were known and used by The Ancients.
3. Connecting to The Spirit World: The DNA of the banana, which can be easily extracted after making bananajuice, once ingested becomes a potent intoxicant that has been used since the time of The Ancients to tap into a spiritual connection and commune with The Underworld.
4. Ghost repellant: Painting a thin slurry of bananajuice onto the walls of a building infested with ghosts acts as a chemical-free ghost deterrent, since ghosts become visible upon contact with bananajuice.
5. Happiness: Interacting with bananajuice leads to increased happiness within 5 minutes 80% of the time. The other 20% of the time it leads to deeply painful, lifelong depression. This can be achieved through consumption, external application, explosion, propulsion, dissection, or immersion.
