There are large quantities of cut content from the soapland 'Honey Bee Inn'. The content is as follows:

Whilst in the club, Cloud could end up in a bathtub with nine muscular men, peep through keyholes of occupied rooms, have makeup applied, and choose a room to stay in. You could have also encountered Palmer, head of the Shinra company's space program, coming from one of his regular "bath sessions". There was also a waiting room and employee's louge which players could visit and interact with NPCs.

Whilst some of this content was ultimately cut from the game, the unfinished content can be found on the discs of the original Japanese release and can be accessed through file hacks.

The inscription on Jenova's helmet is a reference to the real world, and read:

It wasn't until 2005 (When a high-res image emerged) that this was found, 8 years after the game was released.

In the Ghost Square section of the Gold Saucer there is a pumpkin with green eyes in the corner of the room to the left of reception at the inn. Interacting with this pumpkin will cause it to laugh. This laugh is in fact a slightly slower version of the iconic laugh of Kefka Palazzo, the villain from Final Fantasy VI.

On January 17, 2022, the Italian Senate hosted a Zoom meeting about the Transparent Public Service. Just when Nobel Prize-winning physicist Giorgio Parisi was about to be introduced, a user named Alex Spence "zoombombed" the meeting with at least 30 seconds of a CG pornographic video featuring Tifa Lockhart that was originally made by Patreon user JuicyNeko. The news spread mere days after the incident, and Tifa became the subject of memes that associated her with Italy, including being considered an Italian video game mascot that’s on par with Mario.
