only cukes and squash were planted in that area, which used to be a flower garden.

Cucumbers and squash will not cross pollinate as they are not related. Your yellow cucumber is over ripe. The skinny ends can be caused by improper pollination, hot temps or too much fertilizer.

Welcome to NGA, @krystablair !

I agree with Daisy

In my 35+ yrs of gardening i've seen lots o mutants. I believe its cross pollination. A bee just left another garden and polinated yours. I've had sweet italian peppers . some were were sweet some were hot ! Off the same plant #!!! I believe it got crossed with the jalapeno plant. Weird and wild looking squash an cucks too do do do do dot ! It just makes gardening more
FUN! 😎😎😎

Philip, your sweet peppers and jalapeno peppers could have crossed -- but it wouldn't have affected the fruit that you harvested; the cross would have shown up in the offspring grown from the seeds of those peppers. If your Italian peppers were the result of a cross, it would have been a cross between plants that produced the seed that you grew out (or that someone grew out to produce the plants that you bought). There can be a LOT of variation within any given variety of vegetable.

It is an ageing cucumber.
