What do you make of partial entanglement then? Popular expositions always seem to talk about two maximally entangled particles, but this is an exceptional case. Mostly the two particles’ states are merely probabilistically correlated. In that case I can’t see how the slinky analogy works. BTW the maximally entangled case is indistinguishable from the classical situation where two gloves of a pair are separated and then observing one reveals that the other must be the opposite glove. It’s only in partially entangled states that Bell’s Theorem shows a divergence from the “hidden variables” prediction.
