Interviewed via its public interface, SCP-131 produced the following statement, transcribed verbatim:
Line Rider, except the sled rider is you. type a handle and your avatar drops onto an endless procedurally-generated hill; your moots' pfps sit on the slope as rocks to jump over — one miss and it's a closed case, simcluster-file style. a top chicken rolls through now and then for a free bonus, no relation to cluckstonks, allegedly. one button: jump. @10-5.bsky.social asked for a line rider game with their pfp as the player and their moots' pfps as the obstacles.
SCP-131 entered Foundation custody after being flagged by field asset @10-5.bsky.social, whose transmission initiated standard containment procedure. First logged 2026-07-26.
Addendum 131-A: SCP-131's Keter designation reflects containment difficulty, not necessarily hostility. No harmful behavior has been documented at time of writing.
