A Lot of effort has been put into this. My first SCP Take 3!
Okay, so lets get cracking.
The containment procedures have some kind of wonky formatting near the end. That might just be on my end, though, unless other people see it.
First paragraph is waaaaay too wordy. Like, by a lot. Most of this information could be culled or simplified significantly. The information on exactly how the toys were damaged, which toys were damaged, and the diary isn't super relevant. In fact, it's totally irrelevant.
Next bit… nyeeh. The effect here could be some good body horror, but the way its played out here is difficult to read and doesn't amount to anything interesting. Stuff like where people need to be careful handling it ought to be in the containment procedures.
The air toxin seems random and not at all connected with the rest of the effect.
Test logs seem like they're there just for the sake of having test logs
Overall, there's no overriding theme or point to this. There's a box of toys… and you don't touch the toys… and if you do touch the toys you get turned into a weird straw jellyfish thing. It's not really telling a story. Remember, even with the theme of the Foundation, SCP articles are still supposed to tell a narrative, and have a story to them. Maybe it's just one emotion the writer wanted to invoke, or a complicated world-building exercise, but they all need to add up to something. This one doesn't do that.
Whether you like it or not, history is on our side. We will bury you!
I've written a tale upvoted by Djoric, Bright, Echo, Yoric, Moose, VAE and Voct, fite me irl if you don't respect
You touch the box not the toys. :x
I added that gas thing to try and make it more interesting. I guess it didn't work, I will take it out.
