Here are my best SCP ideas right now:
SCP idea #1: It's a designation for two things. One is a star on the Hollywood walk of fame, for a person who no one knows who it is, and the other is a cement block outside of (the former) Grauman's Chinese theater with hand, and shoe prints from the same guy, with writing, thanking the fifth church for all it's done for him. If someone makes anything other then positive remarks about it nearby it, something awful happens to them. Not completely sure on the specifics on what yet. Maybe you get brainwashed into liking him. Maybe you get tortured, mutilated and/or killed.
SCP idea #2: It's the mausoleum of Uncle Sam, or maybe someone named Sam Washington. So it's the mausoleum of the "spirit" of the "old" United States, in a manner of speaking, and if someone of German, Russian or Japanese descent, as well as anybody who has political, or religious beliefs that were controversial, or unpopular in the United States during the early 20th century, comes close to it, it opens up and they get dragged in where horrible things are done to them. Not sure on the specifics of that either. Maybe they get tortured, mutilated and/or killed. Maybe horrible things are carved into their flesh.
SCP idea #3: It's a phenomenon that cause small holes to appear on wooden surfaces like trees or wooden houses. The holes emit a constant chirping, and if a human tries to harm or destroy the holes, huge birds like eagles, condors, ostriches and an actual "big bird" from sesame street climb out of the holes and start attacking people. If a person who doesn't know about it's anomalous effects comes close to the holes and spends some time with them then they'll slowly start to like the holes and "the birds" inside. After a while they'll start to want to feed "the birds" with seeds and such. After a while they'll start feeding it mouses or rodents/gerbils and or other small animals, and eventually they'll just stick their arms into the holes and after about a minute their arms will be gone. The more "the birds" are fed, the more holes start appearing. If the person gets removed from the holes for a while they'll become aggressive, and then they'll become paranoid and terrified of birds and holes, going so far as accusing researchers of being birds in disguise.
And those are my three best SCP ideas right now. What do you think?
