These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Even the Gyroids get looked at from a different point of view. In the games, they're innocent if weird statues of unknown origin that move and make funny noises. Here, they're not so innocent weird statues of unknown origin that mutate those exposed for them for too long (as well as driving them temporarily insane)... that move and make funny noises.
