Gold Nugget

A gold nugget is an item used to make gold ingots, golden carrots, and glistering melon slices.

Zombie pigmen
Zombie pigmen, when killed, may drop 0-1 gold nuggets. When killed using a weapon enchanted with Looting, they may drop an additional gold nugget per level of looting used, up to a maximum of 4. This can be also be used as an ingredient for potion brewing, but it needs powerful when zombie pigmen dies near nether fortunes.

Usage
Gold nuggets can be used to craft a golden carrot or glistering melon for brewing. Also, gold nuggets can be combined with gunpowder and dye to create a firework star that bursts in a star-shaped explosion.
