Beetlejuice, Beetlejuice (2024)
Winona Ryder’s scene was early in the movie, with her standing up and Beetlejuice makes her belly inflate (like Violet from Willy Wonka), until her water breaks and a lil Beetlejuice comes out and bites her ankle.
For the Jenna scene, its very close to the end and is actually a dream, but Winona is watching her give birth in the hospital and she's pushing and then her water breaks and its another baby Beetlejuice, then Winona wakes up.
