Being forced to sing due to technology had to be one of the strangest things the bots have ever ended up dealing with.
The bots did decided to mention some of the 'instruments' they played through their times, which they did end up finding within the old storage in the Sigma. In the long run, that ended up leading to one of the greatest mysteries in which had to be solved.
It started whrn Dani was hearing something playing on night, which happened every few nights. Eventually everyone had heard it too, but they could never catch what i the world it was because when they did stake it out, they got nothing.
Cody knew exactly who it was doing this but he said nothing, and eventually, everyone sort of stopped trying since it wasn't actually much of a bother. The music was pleasent, but it was nice to hear every once in awhile.
But they never found out who it was.
