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.
Fridge Horror: As if it wasn't terrifying enough, the man whose helmet was taken off almost appeared to have been absorbed into the planet's surface, transforming into another blob of eyes and tongues. What if he's still sentient?
Which also begs the question, are all the other eyes and mouths and tentacles on the planet made from absorbed people? And after Earth is eaten, did everyone living there become masses of tongues and eyes?
Narm / Narm Charm: When Remina opens its eyes, it's a horrific reveal that feels just plain wrong. When it opens its mouth, it looks like, as one character so eloquently put it, "A fat kid eyeing a donut!"
The entire sequence where Remina and co. are sent flying literally around the world after the Hellstar licks the planet. It's so ridiculous you can't help but laugh.
"It ate the fuckin' moon!
Nightmare Fuel: Even when you know it's coming, it's still one of the crowning examples of this trope when Remina opens its giant eye, eyes the moon, extends its tongue, wraps it around the moon as everyone watches, swallows the thing whole...and then shifts its eye to gaze directly at Earth and everyone standing in the streets, looking on in utter horror. Mass "Oh, Crap!" aside, it's hard to even get scarier and more terrifying than that.
The Woobie: Remina. As if the malevolent Planet Eater bringing about the apocalypse wasn't enough, almost every survivor the poor girl meets wants to torture and kill her.
