"Eid-al-Fitr" is celebrated after the month of Ramadan ends.

According to tradition, children collect candy by knocking on their neighbor's door on the morning of the feast.

Therefore, another name of this holiday is known as "Candy Feast".

You can find Candy Ore in the depths of the mine.
Candy ores drop Candy Gem.
You can craft Candy Armor and Candy Sword with these gems. (Their strength is the same as the iron items.)
Every time you kill a entity with the Candy Sword, edible candies will drop randomly.
You can fill your a half hunger bar by eating these candies.

These little candies aren't enough for you? Then it's time to make Cotton Candy!
You can make a Cotton Candy Machine.
You have to fill this Machine with Cotton Candy.
You have to combine "Sugar" and "Pink Dye" to make "Pink Sugar" and put it in the machine.
Then you have to place a Stick on top of the machine and right click and run.
In a few seconds, your Cotton Candy will be ready.
You can right click again and get it.
When you eat, your hunger bar will be filled 2.5 bar and your HP will increase by one heart.
