Hi daroyalle437 and welcome!
I did a search on the site and an all you can eat crabfest looks to be a new one! Sounds like a fantastic idea for a family night, though!
Thought I would pass along this link to a Message Board discussion on family nights that include events such as all you can eat pizza nights. You might be able to get some ideas from it:

Also, if you check out our File Exchange, you'll find some great forms that you can download for your fundraiser, including flyers to parents and thank you templates:http://www.ptotoday.com/filesharing/category/142-fundraiser-forms-a-letters?ctid=9
And, you can find some general fundraising management information in this piece:http://www.ptotoday.com/pto-today-articles/article/1004-9-tips-to-increase-fundraising-sales
Good luck!
