Out of sheer curiosity, I found a soundtrack that was different from the others.

Its title is: Room-2A

If you download it, you'll see images of different tracks, but the last track on the soundtrack has a curious image.

Even though it's dark, you can still see something...
If we shine a light on it, we might see someone we know...

It's none other than Lockjaw from TRTF 3!

Therefore, it should be noted that there is a possibility that TRTF 3 Enhanced exists.
