The Rainbow Fruit is a legendary fruit that was rumored to have gone extinct, however one Rainbow Fruit plant still grows in the IGO's 8th Biotope Garden. Prior to the many disasters that befell the biotope and the Human World, the fruit used to be surrounded by a pack of Troll Kongs who used its sweet scent to attract prey, although the current status of the Troll Kongs and the fruit is ensure after the events of the Meteor Spice, although it is presumed they were revived by saiseiyas. The Rainbow Fruit is the Dessert Course in Toriko's Full Course Menu.
The fruit received its name not just from its colorful appearance, but from the way its juice, when evaporating into the air, gives off a rainbow. When placed in one's mouth, its flavor shifts seven times, making the eater taste a wide assortment of delicious flavors. Also of note is that the color and taste of the fruit depends on the humidity and temperature of the air. It's so delicious that most beasts want to eat it by instinct and try to eat it even while being eaten themselves. Because of its intensity, people are cautioned against eating too much of it.
The nectar of the fruit is so concentrated that just a single drop could turn a whole 25-meter pool into a huge bowl of fruit juice. Combined with alcohol, Rainbow Fruit juice is called "Rainbow Cocktail", and it is widely revered and sought after by bartenders far and wide. It can also be made into the strong alcoholic wine simply called "Rainbow Fruit Wine", which has a very high 85% alcohol content.
