This happens to every gardener sometime.  You turn your back on a zucchini plant, or you just don't look closely enough (our case), and you have a monster squash (~8 pounds).  Even when so large it will not be all wasted because both the F1 and her Mother like to make zucchini bread.  Otherwise it gets sold to Elon Musk to use as his next space rocket.  For size comparison a standard 6" juvenile (about 5 oz.) squash was placed next to it A 25 fold enlargement in just a few days.  Gadzucchini!
