Also wow! Never knew they put me in the Cursed Library as an easter egg
Edit: in actuality though, I might have found something possibly interesting
The deholder has a projectile called “HyPEr rEalIsTIC BLoOd”
There is a creepy/troll pasta called Hyper realistic that goes like this:
One hyper-realistic morning, I opened my hyper-realistic eyes, only to find that my hyper-realistic sheets had been torn off my hyper-realistic bed and strewn about my hyper-realistic room. I decided, with my hyper-realistic brain, to jump out of my hyper-realistic bed to find the cause of this, only to notice that, when my hyper-realistic feet touched the hyper-realistic carpet, it was damp.
Looking down with my hyper-realistic eyes, I saw that it was covered in hyper-realistic blood. I opened my hyper-realistic mouth to scream, but hyper-realistic blood started to pour out, and my hyper-realistic eyes became filled with hyper-realistic blood-tears. Due to a massive loss of hyper-realistic blood, I died, and then a hyper-realistic skeleton popped out.

I feel like some things here might link to the deholder, like the blood pouring out of the eyes and blood-tears. Or this could just be completely unrelated lol.
Edit2: Adding onto that, I’ve also been looking at descriptions for monsters and for the deholder it says:
In the xml there are columns with the model of Candy Col Whole:
I feel like this is a rather odd model name considering the candy part. Col could simply be for column, since these are describing pillars, and whole could just be a model adjective, but candy sticks out to me for one reason or another.
