Cacao fruit are fruits that can be found on cacao trees, spawning every X days. They can be eaten raw, but are more useful when cooked into the eventual cookie. They can be difficult to obtain on random islands due to the fact that the trees may not spawn naturally, but they are dropped from the crates that randomly appear in the sea, making them available to plant. They can be very useful in survival due to the fact that many cookies in a stack can replenish much hunger for a relatively easy gain.
The part of the cacao fruit that is actually known for making chocolate is the cacao (or cocoa) seed, which is commonly but incorrectly referred to as cacao beans. The item in the game represents the entire fruit
