Igor

"Lady Bow told me not to sell anything to Mario. You're him."

- Igor

Igor is the Boo that runs the shop in Boo's Mansion in Paper Mario. When Mario first enters the shop, Igor will refuse to sell him anything under the orders of Lady Bow. Once Lady Bow has joined Mario's party, Igor's shop is open for Mario. There is also a letter that Mario can deliver to Igor for a Star Piece. Goombario's tattle for the Boo states: "He probably was a merchant before he became a Boo."

Tattle

 * This Boo runs the shop. Nice selection, huh? I'm sure he's cornered the Boo market around here. Maybe he was a merchant before he became a Boo. I bet Bow orders most of this. – Goombario
