>>26846585>>26849698I've always thought these were remnants of the skull teeth.
I mean, it's obviously that Dusclops keeps the skull under the bandage since the shape of the teeth can be noticed.
These rectangular shapes can also be seen coming out of Dusknoir's neck, so it has always seemed to me like Dusknoir's skull got "inverted" and deformed in a macabrous way leaving the teeth literally twisted up.
Headcanon tier I know, but still.
