Yes, they can get pretty big, 30 inches, 10lb easily. They are easy to grow too. The plants last longer than other squash plants(they are still growing in my garden now), and they don't seem to have the pest issues as other squashes. The fruits can be used young or kept for a long time as you need. The young leaves are edible and delicious as well. If you need seeds, please contact me, I have plenty.
