Peach

The Peach is one of the two Apples that are not necessarily apples, the other being the Waterfruit. The Peach was added during the series of updates giving us numerous different types of apples with different values; however, it is currently unused.

Appearance
The Peach is a pinkish color with the Plastic material. Its pink, however, is still a similar shade to that of the Apple, Earth's Apple, and the Papa's Apple, making it very confusing.

Occurrence
It's currently unused in the game, and it's not known as of this moment as to when it will be added as a full feature.

Point Value
The Peach is the only Apple that awards no point value on pickup, going so far to even show that in the popup message when you collect it. This makes mistaking it for the other mentioned Apples very frustrating and tedious if you are trying to get to a certain goal.
