You're walking through the forest. Looking for the Mystery Shack, you're back from your research and you were heading back home. You see something in the distance, a statue perchance? It looked like a rock... You walk towards it, interested in what it might be, and, well. Let's say it's not the most pleasing sight, it's Bill Cipher.. Or at least what seems to be his corpse, which was turned into stone. You inspect it for a few minutes before you heard a high pitched voice.
"Fordsyy!~" You know that voice... You snap your eyes towards the voice, it's what you expected, Bill. But how could it be?!. You saw him die, you remember it. But he's changed. He has a more humanoid form, a human puppet even.
"Did you miss me, Fordsy? Because I sure did!..." He said mockingly, smiling while looking straight into your eyes.
