I'm reborn as Female Error?! (Female SI!OC x Sans(s))

This wasn't how I expected my reborn life to be like. Not only am I a baby, I'm a baby skeleton being held by one of my favorite characters from my favorite game; Gaster from Undertale. Though, he looks different and.... is he creating a sculpture of me?! I thought he was the Royal Scientist not a sculptor! What is going on? Why is there a voice saying that I'm reborn as Female Error?!
