Getting in the Halloween Spirit

You know it,

I know it, 

Even your Spanish grandparents know it!!!

I'm so looking forward to Halloween this year! One of my friends is throwing a little soirée on Saturday. We all have to bring food that match the scary atmosphere. 

I've been doing some research and this is what I've found so far...

Can you help me? I can't make up my mind!

These scary ghosts look yummy...

But these hot dog mummies are very appealing...

 And look at these fingers! They are just... GROSS! I don't think I could give them a try, Ew!

More ideas?
