Also, I'm undecided as to whether or not it's too similar to [http://www.scp-wiki.net/scp-136], so thoughts on that would be nice too

…I'm still fairly new to the site, but it looks like this is #6 and #11 from the big cliche list (a thing what makes you go nuts for no apparent reason and a thing what performs OTT (Over The Top) as to what it's supposed to do - scarecrow what scares ppl to death).
Besides that, it seems fairly standard. It really just scares you to death. This is where I think the [EXPUNGED] hurts your SCP; maybe if you had a list of effects, and ended it with [EXPUNGED] entries. But that might not be enough; the primary effect isn't super interesting yet.
Maybe if you expanded on the effects, and changed it from a scarecrow to an adorable teddy bear… or stuffed unicorn… or even something mundane, like an ordinary 22-oz water bottle or an iPhone or, I dunno, a giraffe.
Grammar nitpick: look up the difference between 'it's' and 'its'.
