As you can pretty clearly see, the dildo in question (named “Jewel of the Amazon”) mirrors the color and texture of the Amphibian Man’s body from the movie.
We never actually see his penis at any point during the movie, but that seems like a reasonable approximation, especially since one of these was definitely not a part of Doug Jones’ monster suit during the film.
This writer is admittedly not an expert on movie-inspired sex toys, but I am willing to bet that’s the only dildo that you will find that’s inspired by this year’s crop of Best Picture nominees — unless there’s some bizarre Dunkirk vibrator out there that we haven’t found yet.
