Honestly, that puppet is always horrifying but I'd be lying if I said the scariest parts to me aren't the parts where the MC is interacting with ...well basically anybody but especially his uncle. There is just such a sense of wrongness that's even worse than wtfever that thing has going on!

The water is semi-transparent

If you have not seen Possum, so long as you aren't too arachnophobic, I highly recommend it!

The MC is a disgraced children's puppeteer whose main puppet is an absolute horrifying spider-bodied thing with a replica of his own face.

Slow-burn but immensely disquieting & uncomfortable horror movie.
