As of late, I've been considering numerous things which could make.. decent at most SCPs, if not neat anomalous items. However, these are just the base items, not the properties that make them SCP worthy. So I'm tossing them at you guys!
An umbrella, a walrus, thumbtacks, and a loudspeaker.
I'll probably update this as I think of more things to add. By all means, if you get a spark from one of these, write it up!
