At the beginning of Bird Box, Malorie tells the children
Boy, you have your dog. Girl, you have your kitty.
We later find that the Girl's cat is her mother's Hello Kitty plushie. What was the Boy's dog?
Did I miss something in the movie?
In the scenes where she's putting the kids into the boat, right in the beginning, there is a shot from behind the kids. You can see a small dog toy on the bag of the boy. While it wasn't a baby shower gift, we can assume that they picked that up on one of their regular supply runs.
The novel has a real dog that they adopt, they find by the side of a dead family. But in the movie, it's just a toy.
