It is a small closet with three shelves. The middle shelf contains a cassette tape with a recording from Sammy Lawrence, some non-lighted candlesticks, a bowl of spheres, and four obtainable cans of Bacon Soup.
Wally Franks mentions in his second audio log that he cannot find his keys anywhere before opening the closet's door for the dustpan.
The closet can be only opened with a key which can be found from one of the garbage cans. After finding the keys and opening the closet beside Sammy's office, Henry will find a voice recording of Sammy Lawrence, which gives him a hint about the upcoming music puzzle.
Wally's dustpan is later stolen by Sammy Lawrence to use when hunting for Henry, as noticed when visiting the closet again after activating the pump switch from Sammy's office.
In the old updates before the release of Chapter 4, the dustpan was not added yet.
During Chapter 2 remaster development, theMeatly leaked an image of Wally's dustpan.
