Somniosus

MOM!

Object class: Euclid

Special Containment Procedures: Impossible to contain. A number of operations have been made in order to pursue the entity, but no corporeal form has been found. Since the SCP hasn't shown any signs of lethal action, containment isn't considered an emergency.

Description: SCP-030-J is a phenomenon that makes small to medium objects disappear when the subject looks for it. It operates worldwide and can't be willingly summoned, thus only appearing to subjects who are entirely unaware of its existence. Trying to provoke SCP-030-J upon an oblivious subject also has been proven to be ineffective. It usually manifests during stressing situations, though is not uncommon to be affected by it during mundane tasks.

Discovery: Though the disappearance of common objects wasn't anomalous enough to be classified as an SCP, Dr. ███████ made an interesting observation regarding SCP-030-J a few weeks prior to its classification. He was looking for his missing water flask when he asked Dr. ██████████ for help and she said: "You never find anything" and proceeded to go straight to his lost water flask, placed under a desk.

Similar responses have been provoked since then and several subjects have been put to test when personnel report missing items. Results were conclusive: SCP-030-J responds directly to female subjects that are either pregnant or have one or more children and passive-aggressively help its victims by reproducing sentences like "If I go there I'll find it!" or "You'd lose your head if it wasn't screwed on!".

Addendum 030-J: Always thank her.
