Ms. Mowz

Ms. Mowz is the optional character and the seventh and final party member in Paper Mario: The Thousand Year Door.

Mario encounters Ms. Mowz at Hooktail Castle, the Great Tree in Boggly Woods and the Glitz Pit storeroom. She is a badge hunter who also happens to be the assistant shopkeeper at the Lovely Howz of Badges.

When Mario goes to the Trouble Center and accepts one of the troubles, namely the one marked "Elusive Badge!", he finds that it is Ms. Mowz who put the trouble up. She asks Mario to find a badge in Hooktail Castle. When he finds it, she reveals that she hid it there herself to test Mario's skills, and if he can find badges then she wants to be with him. She joins the party. At the very end of the adventure, she continues running her badge shop.

Ms. Mowz is a thieving mouse who runs a Badge Shop at Rogueport and constantly flirts with Mario. She's the only optional character, and you have to accept a Trouble and find a Badge for her in Hooktail Castle before she'll join you. She has the useful ability to sniff out any type of item, ranging from coins to items to Star Pieces, although this ability is more like playing hot and cold than a straight answer. Similar to Watt's ability from Paper Mario to show hidden items. She also possesses the ability to cut through Defense. Her Japanese name is Chuchuriina, which is based on "chuchu" a Japanese onomatopoeia for a mouse's squeak.
