soda fruit is commonly found in the mountains of boinkus island, located just off of Dominican republic and Haiti. its strange, jello like properties are unlike most normal fruits, but the true secrete is inside the fruit. if you try to drink the fruit(via the straw), its rare juices inside, commonly known as yummy soda will give you a quick rush of energy, that is about twice as powerful as coffee, this is used regularly every day to get around without using cars.
Pretty much just "Bonk! Atomic Punch" from Team Fortress 2.
