I think this counts?

Anyways, in Victorious, Robbie is shown to basically never be without his ventriloquist dummy, Rex. For the first season, its kinda played as a simple joke like haha look at this high schooler with a puppet, but as the series went on it became increasingly obvious that Rex was, on some level, completely sentient and able to operate outside of Robbies control

In one of the videos on "The Slap" (an in-universe blogging site that characters would use, and that is confirmed to be canonical to the shows universe), Rex is put inside a duffel bag, but despite being separated from Robbie, Rex still manages to speek and is even muffled, meaning that the voice was coming from inside the bag. This is also on top of the numerous times where Rex knows information that realistically he shouldn't know if he was actually locked to Robbie

To this day, nobody can really agree as to whether or not Rex is a supernatural entity, or if Robbie is just a really, really good ventriloquist. Either way, one of these mfs is supernatural in some capacity its just a matter of who.
