George: "The want to fit into a society you feel alien from being symbolized by a strange instrument wailing the melody, alone, in a song filled with instruments got to me."
History: Pet Sounds is a Parrot raised alongside the Falcon Stand user Pet Shop. Both were taken in by DIO after he killed their trainer. The Speedwagon Foundation rescued and relocated Pet Sounds. In 1999, Pet Sounds was stolen from its new home and ended up in Morioh.
History of creation: Pet Sounds and its unnamed Stand were created for the spin-off/ Part 3 sequel/ Part 4 prequel Crazy Diamond's Demonic Heartbreak. In which Hol Horse and Josuke Higshikata work together to capture Pet Sounds.
Abilities: Pet Sounds Stand can make people replay past events remembered by Pet Sounds. The ability is activated when Pet Sounds repeats a sound or voice associated with said memory. At one point, it causes Hol Horse to repeat his attempt to kill DIO on Josuke's grandfather and Josuke to witness the memory of Daniel J D'Arby's first interaction with DIO. When the ability is undone, it's visualised as punch cards shooting from the victim's body.

Trivia: While the Stand is unnamed in the story, through my own research, I have found that it may be named Seshat, after the Egyptian Goddess of writing, wisdom, and knowledge.
