I’ve yet to see a clear answer on this. My understanding was that quantum events occur when a particle interacts with another particle in such a way as to yield different outcomes depending on its spin (essentially “measuring” the spin). There are exactly two possibilities and the world only splits into two.
It’s not at all clear that you can arrange the possibilities into a world where a sperm whale spontaneously appears. I would love to see a correction or further explanation.

Spin is popular for examples and experiments, but it’s not fundamentally special; all physical properties are subject to QM in the same way.
