The mansion steward is a character that appears in Paper Mario: Sticker Star.
The mansion steward is a Paper Magenta Toad. He also speaks in a very polite manner.
Mario and Kersti found the mansion steward sitting outside of his mansion shivering in the cold. He told Mario that many "terrors" have been released into his mansion from the Book of Sealing. He requested Mario to help him and gave him the Book and Mario heads inside. After Mario captures 99 Boos, he headed back outside and finds and defeated the last Boo, which was hiding in the Steward's fireplace. Mario saw the Mansion Steward after he got rid of all of the Boos and gracefully thanked Mario for his help; he allowed him to return anytime.
