Jupiter of the Monkey (also known as J of the M) is one of the game's 13 brands. It represents the Monkey in the Chinese Zodiac. The name of the brand may also be based off the Japanese language of the Monkey King, as Jupiter was the ruler of the gods in Roman mythology or a reference to the game's co-creator, Jupiter, and to the Aesop's fable Jupiter and the Monkey. Jupiter of the Monkey has one main store located in Cat Street. Pins may also be sold in Edoga and AMX.
