Stepmom

""There's nothing worth hiding, Giorno! Say it, Giornooooo! Say it!" he rose to a shriek at the end, and his Stand appeared behind him. It looked like a girl, and held a needle and thread in its hands."

Stepmom (継母 Mamahaha) also written as Goodnight Moon (グッドナイト・ムーン Guddonaito mūn) is the Stand of Bruno Bucciarati from the 37th universe that is featured in the novel JORGE JOESTAR.

Abilities
"If you don't tell the truth, I'll stitch your mouth closed!"

- Bruno Bucciarati

Stitching
Stepmom's main ability is to sew things together at an incredible speed. It was first seen use by Bucciarati, who, after learning Girono was lying, sewed Giorno's lips shut.

The way the stitching works is by putting the needle through the targets, pulling it, then begins sewing.
