The EndLands

A new biome in the end that is extremely rare and hard to find harboring natures supper food and even more dangerous mobs.  The Endlands would contain an extremely rare sand, end sand. The end sand would give life to the Cyanococcus Plant aka the blueberry plant, the blue berry plant would only drop blueberries 10% of the time making them hard to farm and only able to live on end sand, blueberries would only deliver half a hunger point/bar and would deliver 4 health points/ hearts in return, the plant would also have a 1% of the 100% to drop poisonous blueberries witch would do the opposite. the danger with traveling out that far in search of the endberries/blueberries is the new mob that would live in the new sand and behave like silverfish, except they would not destroy the sand, the sandfish would appear out of nowhere and inflict 1 heart of damage with no Armour or buffs, and inflict blindness and nausea for 5 seconds. The Endlands would be small islands making the risk of walking off and falling into the void prominent. If you do not take care of the growing numbers of sandfish they will overwhelm you and push you off the island.
