Warning! Unmarked spoilers below!
- The Homunculi in the remake eat human teeth. Gee, thanks for making us paranoid of the Tooth Fairy, Del Toro. Again.
- The opening scene. Blackwood graphically kills his maid by forcing her teeth closed and then smashing them. He then collects the bloody teeth in a bowl to serve to the Homunculi in return for his son. All we can hear is their voices from the grate, and worse is that we can hear Blackwood's son crying for help. Blackwood reaches out for his son, and then the Homunculi come and drag him down the grate with them.
- After opening the grate, Sally's teddy bear activates and speaks. Sally, enamoured, approaches and reaches for it, not noticing what the audience can...that two of the homunculi are just behind it.
- The shot of Sally's doll on the floor as she searches for it after a little Jump Scare from the homunculi. We later see it with its mouth chewed off in an attempt by the "tooth fairies" to get its teeth.
- Shortly after, Sally begins searching for the homunculi in the dark, with only the light of her music box. We see the floor under her bed, where DOZENS of them are scurrying along beside her, peeking out, though too afraid of the light to come out. The fact that you can only see their shadows and the light of their eyes is creepy, to say the least.
- Blackwood as a Homunculus, particularly due to how his deep voice is so jarringly different from all the other creatures' high-pitched ones.
- Blackwood's mural in the basement, showing a young child being dragged into a hole by long, black arms, with white eyes peering out of the darkness.
- Blackwood's paintings of the homunculi are pretty creepy. It's explained that he used to be a wildlife painter... but his obsession with learning about the homunculi caused him to switch subjects. It's no wonder his family didn't want his final paintings published (the fact that, according to the prequel, he was ostracized from the scientific community for his new found interest in the supernatural probably didn't help).
- In the climax, the Homunculi shut off the entire house's electricity and go all-out in trying to capture Sally, with the parental fears going into overdrive. During this segment, there's a scene where Kim is knocked down the stairs, falling over a wire similar to the one used to trip the maid at the start, set by the homunculi. There's a shot from her POV from where she lies dazed on the floor of the homunculi slowly crawling towards her through flashes of lightning, each time growing closer, their eyes shining in the dark.
- The ending. Kim, who sacrificed herself to save Sally, has been transformed into a homunculus, and is now plotting with the other homunculi to wait and bide their time until they can escape.
