Planning Mac's Birthday

I am in the process of planning Mac's 4th birthday party.  Here is where I am at so far in my planning...

Theme: Superhero
Location: Alaska Club West Play Center
Invites: Done by the fabulous Morgan
Colors: Basic colors, black
Party signature thing: Superhero hardback book (got an Ironman book)

Food:
          Pigs in a blanket (Wonder Dogs)
          Fruit variety (Pick your superpower: strength, mind reading, super speed, laser vision)
          Sandwich sub platter (Heroes)
          Cake vs. cupcakes?
          Rice crispy treats (Kryptonite crispies)
          Pretzel chocolate sticks (haven't figured out a cute name, thoughts?)
          Drinks (hero hydration)
          Cheese sticks (elasta cheese)

Decorations:
          Tablecloths- maybe in the bold colors blue red yellow black
          Comic book M
         "Buildings" for the food table
          Comic book banner

          Superhero Pez Dispensers
          Something for the "babies"

I saw this lady got a "doll" house online (Link is right here -----> superhero house) and turned it into a superhero house with superhero peg people.  I am DYING to do this for Mac but I need to find something.

Drinks (gonna do water bottles and juice boxes)
Cheapo comic books for decorations
