SCP Foundation

… Goldfish don't have stomachs. Their digestive systems are straight tubes from one end to another.

Are we sure the sudden increase in the rabbit's ability to smell killed it? I have experience in the matter, and I believe rabbits kill themselves of fright just for fun. It's sad at first, but after hearing about it over and over again, it's actually quite annoying.

In combination with SCP-038 and SCP-112, this could be used to introduce completely new species into the world

Man, I surely miss some last unusual experiment with the result being EXPUNGED here :)

Kind of creepy, at least to merit an upvote, but it could be way better, and the bunny part sounds kind of LoLfoundation, at least to me.

It's okay, could be better though. a few suggested changes.
"that contained neurotoxin deadly enough to kill a Class-D in under ten seconds"
to "that contained a deadly neurotoxin capable of killing a man in less than 10 seconds". The use of "deadly enough" sorta breaks the tone for me.
"appears to be two hundred (200) to two hundred fifty (250) years old," to "appears to be between two hundred (200) and two hundred fifty (250) years old"
"If the mutated specimen dies as a result of its mutation, the effects of SCP-783 stop." to " The effects of SCP-783 stop if the mutated specimen dies as a result of its mutation"
Also, try assigning numbers to D-Class personnel, as well as some information like age and sex.

Is the male beetle laying eggs a part of the SCP, or just a typo? Or did I misread that entry?

These are all, not… great… the notion that the foundation would lock a D-Class (believe it or not, they don't have an infinite number of them) in a cell with an anomalous animal, having absolutely no idea what will happen and having no possible scientific insight to gleam from this, and allow it to do… that… to her, is completely ludicrous and screams of that LOLFoundation stuff that was popular at the time this was written. Being fair, it was a different era, and the folks on here were a lot younger and edgier, but boy oh boy this needs a rewrite. Hopefully Dexanote finishes this up at some point.
