Who cannot extant; a specialist of sundry.
Giver of the world, feeder of the unhungry.
Who cannot extant; a specialist of sundry: To "extant" means to exist; it is the antonym of extinct. The Magicant Merchant cannot actually exist because he isn't actually real.
Sundry is a term used for miscellaneous items. When you talk to him he says, "Hi! This shop specializes in puddings and pendants!"
Giver of the world, feeder of the unhungry: He sells you the "Earth" pendant and Magic Pudding. The Magic Pudding only gives you PP, so it won't help you if you need to restore your HP.
