can this bee explained

This definitely does not belong here but it is odd and doesn’t really belong anywhere else either: my grandson loves freezer pops the kind in the plastic tube that you freeze and eat. We discovered Snapple Sorbets. We ate them all summer long. Their taste was a little more adult favor, He and I fought over the mango flavored one.
The last box we bought had two sour apple tubes and one would not freeze. It is still in the freezer after 3 months and hasn’t formed a single ice crystal.
What could ca8se that? Is it safe to eat/drink? Were the others safe to eat—skip that it’s too late now. Would you buy the product again?

1. What temperature is your freezer set to?

If zero degrees Fahrenheit, that's cold enough to freeze saltwater. So I suspect your freezer isn't quite as cold as it should be. That or those tubes are mostly antifreeze. Simpler explanation is generally the correct one.

2. "adult flavor" is the key here.

The flavor of sour apples possibly fermented, which means alcohol which means the freezing point was lowered most likely. Thats my guess on this

On edit: most likely safe to eat/drink if you like apple vinegar wine.
