Jelfonzo

"This Jellyfish gentleman goes by the name Jelfonzo, and he runs Ye Olde Cloth Shoppe. And check out his origin story: one day he just split off of Jelonzo in Inkopolis Plaza, and there he was! I think that makes him Jelonzo’s son? He apparently learned to speak Inkling from an ancient text of some sort, so his speech sounds a bit outdated (to say the least). But don’t let that fool you. When it comes to fashion, this dapper dude is always up on the hottest trends."

Jelfonzo is a character in. He is a Jellyfish who operates Ye Olde Cloth Shoppe.

Description
Jelfonzo apparently "split" off of Jelonzo, the Jellyfish responsible for running Jelly Fresh, Ye Olde Cloth Shoppe's equivalent in Inkopolis Plaza, and therefore could be considered Jelonzo's son. He studied the Inkling language through ancient texts, thus adapting fairly outdated terminology (as demonstrated in the name of Ye Olde Cloth Shoppe). Despite this, he is still up to date with the freshest trends.

Trivia

 * Jelfonzo's Japanese name is "Bizen", and Jelonzo's Japanese name is "Echizen". These two come from the provinces of ancient Japan.
