Can anyone identify this? It came from a volunteer vine

13. Last year my zucchini and acorn squash...

Got together and had some fun under the leaves. They cross pollinated, I had no idea the acorn squash seeds I saved from the fruit must have been contaminated with zucchini “DNA” .
Because this years seeds did really weird stuff…some are round Acorns squash no problem…some are zucchini with a slightly harder skin, if picked early it’s fine, if not inedible…but some of those are showing characteristics of an Acorn, albeit oblong…we”ll see.

I sliced open one of the squash’s and it looked similar to those pictures.
