The story starts with this line: "I just want to start off by saying if you want an answer at the end, prepare to be disappointed. There just isn't one." No, author. That's just lazy writing. And no, "there just isn't one" is not a good enough excuse.
The other two paragraphs after that are fine, but in this line the author just changes tenses out of nowhere. "The happy-go-lucky music plays as is normal. The story began with Squidward practicing his clarinet, hitting a few sour notes like normal."
First, "as is" should be by itself, and not with normal. Or you can remove the "is" and just say "as normal". Second, "The story began" is in past tense, but the first line is in present tense. Therefore, it should be "The story begins", not "The story began".
Also, another instance of incorrect tense is in this line: "This is when things began to seem off." Began is in past tense, but the lines before were in present tense. It should be "This is when things begin to seem off." and not "This is when things began to seem off." Pick a tense, author.
Also, when it's animation, hyper-realistic is not the correct term. The author should've said photo-realistic instead of hyper-realistic. Throwing hyperrealism into your story doesn't make it scary.
The rest of the lines after that are fine, but the part where the author mentions dead children... it's just thrown in for shock value. Scares with no buildup are just not scary. Hear me out. If you don't build up your story, no one will get invested. Don't make it boring, but don't throw all the big punches either.
Keep your scares subtle next time and keep the reader guessing until the end (and by that I mean a proper ending). Gore on its own isn't scary without a buildup. Whoever wrote this, consider this a lesson for next time you write a creepypasta.
