I need ideas for my mod GTMA

I am currently working on a mod called Genuinely Too Many Additions, or GTMA, (https://mcreator.net/modification/67452/genuinely-too-many-additions-gt…)  and I would like ideas.

The ideas I'll accept are virtually anything; new enchantments, new biomes, new recipes, paintings, anything Mcreator can make.

I will credit the additions in a book I will add, with whatever name you would like to choose

If you would like to add to the theme of what I'm attempting to make the next update (0.4) be, the theme is basically any non-generic horror character or beast (other than a select few exceptions like the Mothman or Chupacabra), though the theme can obviously be delayed or be split between community ideas and the horror characters 

Thank you in advance,
