Ring, ring. Why ringing? About 10 minutes ago, my curiosity got the best of me. I visited a game called "Payphone" and walked up to the payphone model. The description said to say "5 ROBUX" and you would be able to call. So, I said it and... to my surprise, my phone rang. It was from this mysterious number. I picked it up and my character reset. But, strangely, the death sound appeared in the call. I left, and it hung up.
I continued getting these calls when I joined any game. Do you know what it is?
