Mr. Shopkeeper

Mr. Shopkeeper is, unsurprisingly, the shopkeeper of Mr. Store who sells multiple products in the Mr. Accessory line, such as: Mr. Accessory, Uncle Buck, Golden Mr. Accessory (one of which was defective), Mr. Accessory Jr., Sister Accessory, Ms. Accessory, Mr. Shirt, Mr. Container, Mr. Eh?, and, possibly, Mr. Exploiter (although this could've been created by the Penguin Mafia, or more specifically Uncle P, as it was sold in his store). He also sells Items of the Month, Year, Monster Manuel, Boosty Juice, Fly-By-Knight Heraldry forms and Custom avatar forms. When the Kingdom became infected with zombies, Mr. Shopkeeper also got infected.
