Emergency Locks

Emergency Locks is a room made by someone. Their name can't be visible, though it probably is made by Mah_Bucket

Appearance
In the room, there is a black sign reading "Emergency Locks" on the top. When you enter, there's several (probably 12) locks. You can input a key into any of the locks.

Trivia

 * There is a hidden, glowing, cyan lock that can be found in the bottom right corner of the room. When you input a normal key to it, it plays the Undertale attack sound effect. If you insert a Sans Key, it spawns in about 15 more of the same key and plays Sans' Dialog sound with each key spawned. After the process is done, the keys will despawn rapidly, and will consume the original key, preventing further usage of the inserted Sans Key.
