Ms. Mowz is a Squeek encountered in Paper Mario: The Thousand-Year Door. She is the only optional party member available in the game; and depending on when the player acquires her, she is either the sixth or seventh member to join Mario's party. She is known to constantly flirt with Mario, which tends to annoy Flurrie and Goombella (the latter occasionally calls Ms. Mowz a floozy) as well as make Koops envious on at least one occasion. She has the useful ability to sniff out any type of item (similar to Watt's ability to show hidden items in the first Paper Mario), ranging from coins, items, Star Pieces and invisible ? blocks; however, this ability is more like playing hot-and-cold, as straight answers are not given. In battle, Ms. Mowz possesses the ability to cut through Defense. She can also steal enemies items and badges during battle with the move Kiss Thief.
