Just discovered your Worm off the String au. How does Dani come into being in this version? Manufacturing defect (non-derogatory) from the worm-on-a-string factory? Vlad collecting discarded fuzz from Danny?
Vlad, being the creep he is, stole shed fur over the course of a few months to make Danielle. However, he does not work in a worm-making factory nor does he know what he's doing or have the proper supplies for worm-making.
So Danielle happens! Unfortunately for her, she does not have a factory-issued string, her string is weak and prone to fraying. Which may potentially result in breaking. (like destabilization)
