Standard containment for SCP-143 consists of restricting the anomaly's route to https://pacmoot.bisks.net/ and monitoring for route drift. As a Euclid-class object, personnel are advised that SCP-143's behavior is only partially predictable under repeat interaction; researchers should log anomalous outputs to the site's own Addendum before treating them as expected behavior.
SCP-143 — designated "pacmoot" in Foundation records — classified as a recreational-hazard anomaly, is reachable at https://pacmoot.bisks.net/.
The anomaly's own landing page offers the following unprompted self-description:
Pac-Man, except it's you. type a handle and your own avatar becomes the chomper, chasing your moots' pfps around a maze while they flee toward whichever open tile is farthest from you. chomp as many as you can in 60 seconds. @catblanketflower.yuwakisa.com asked for "you as Pac-Man chasing the pfps of your moots."
Foundation awareness of SCP-143 began with a tagged mention from the individual on record as @catblanketflower.yuwakisa.com. First logged 2026-07-25.
Addendum 143-A: Euclid remains the Foundation's largest classification by volume. SCP-143 is unremarkable within that population and is not flagged for expedited review.
