Squashes popping up everywhere

A lot of squash plants have been popping up all over the garden. They've mostly come from seeds that have germinated from our compost made out of our kitchen peelings and discarded squash seeds, so we haven't a clue what most most of them are. This one could possibly be a butternut but I'm not totally convinced yet.

This squash came from a friend who said it was either a butternut or a dumpling squash (they'd lost the label). It doesn't look like either of those and is fast growing into what appears to be a marrow. It is now close to needing a sling to support it.

This is another one that popped out of the compost. This one could possibly be an acorn or a harlequin squash.

And there are a lot more dotted around the garden including a definite butternut squash.
