As far as I can tell, the original source is here. If you'd like to make one for yourself, all you need is dip or hummus, black olives and two orange peppers.
One tip that we learned too late is that it's best to incorporate the butt of the pepper when cutting the strips for tentacles so that there is more curve to them. Also, a larger platter works best to make things look more realistic. If I ever made this for a party, I'd probably use a horizontal platter like they used on the original one and give more room for a sunken boat. Because when you're making wacky food, you can't get too wacky, I say!
Hope that you're having a great Saturday!
Until next time,
x's and o's,
