I would like some help please. I am looking for a story where Spike's egg was actually just a painted rock, and in "hatching" him, Twilight created him. If I remember correctly, the story has Celestia telling Spike and Twilight this, causing Spike to breakdown, before Twi helps him realise she is his mom.

Mmm I know of one were spike was actually a doll and twilight accidentally bring him to life

I don’t know if this is the one you’re thing of
But it is a story where that happens:
