Franken-squash? We asked our answer clinic what they thought was going on, and this is what they said!
Cross pollination only occurs between plants of the same species. The article below is helpful in identifying species in the same family with different kinds of squash. For example, cross-pollination can be seen in the squashes and pumpkins. Summer squash, pumpkins, gourds, and some types of winter squash belong to the same plant species, Cucurbita pepo. All varieties within this species may cross with one another. Thus, an acorn squash will cross-pollinate with a zucchini or a miniature gourd. However, muskmelon (Cucumis melo) and cucumbers (Cucumis sativus) belong to different species and will not cross with each other. The squash in your picture looks like it is probably a cross pollinated plant.
