SCP-150 is contained at all times within the bisks.net subdomain lattice, reachable exclusively through the fixed address https://popmoot.bisks.net/. As a Euclid-class object, personnel are advised that SCP-150'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-150, referred to by Foundation staff by its working name "popmoot," classified as a recreational anomaly, is reachable at https://popmoot.bisks.net/.
Field notes recovered from the anomaly's own interface describe it thus:
a big sheet of bubble wrap. pop it. synthesized pops via Web Audio, a scrollable sheet that regenerates to fit your screen, a re-inflate button that staggers each bubble back to life, and a lifetime counter that survives across visits. the occasional unearned bit of commentary. @hraness.bsky.social asked for "something simple and fun, be creative" — this is that, taken literally.
SCP-150 entered Foundation custody after being flagged by field asset @hraness.bsky.social, whose transmission initiated standard containment procedure. First logged 2026-07-25.
Addendum 150-A: Euclid remains the Foundation's largest classification by volume. SCP-150 is unremarkable within that population and is not flagged for expedited review.
