The Old Man Mask

The Old Man Mask is a living mask which is worn by Steve Boswell in the thirty sixth book in the Goosebumps series, The Haunted Mask II, as well as its television adaptation.

Book
Steve Boswell, tired of being constantly bothered by the kindergartners he coaches for soccer, wants to get a creepy mask like Carly Beth Caldwell got the previous year in hopes of scaring them for Halloween. Carly Beth eventually gives in and tells Steve and his best friend Chuck Greene that she had gotten the mask from the party store in town. Steve and Chuck sneak into the back of the store, where Steve finds a particularly creepy old man mask, but the kids are eventually caught by The Shopkeeper. He threatens to call their parents, but Steve pleads to the shopkeeper to let him buy the mask. When the shopkeeper refuses, Steve runs off with the mask.

The next day, Steve finally gets to put on the mask. But when he does, it feels like his body is burning. He's becoming weak and frail. White hair and spiders begin to come out of his ears. His voice is even more old and raspy. What's worse is, he can't take the mask off. Steve tries to call Carly Beth, but gets her father instead, who isn't happy that an old man is trying to call his daughter. Steve, weak, heads out of his house and eventually finds Carly Beth and Sabrina. At first she's scared of him, thinking he's a creepy old man trying to hurt her, but he soon reveals that he's Steve. He asks how to get the mask off, and Carly Beth tells him that her mask came off with the aid of a symbol of love. Steve tries the black and white cookies that his mom bought him, but his terrier Sparky ate them. He tries to hug Sparky, but that doesn't work either.

Steve, Carly Beth and Sabrina return to the party store, hoping to find an answer. They find an old tuxedo, which they put in front of Steve. Suddenly, the mask detaches from Steve and attaches to the suit. The suit and mask dance away into the night. The kids are relieved until they run into Chuck who puts on a gorilla mask he stole from the party store.

Appearance
The Old Man Mask is a disgusting, foul smelling mask with yellow hair and scabbed skin. The mask is crawling with realistic looking spiders, while it grins an evil, single-toothed grin.

Powers
Unlike Carly Beth's mask, Steve's mask makes his body feel old and weak, essentially almost killing him as his body rapidly ages and deteriorates.
