Isn't That Pinteresting: Birthday Edition

My sweet lovable boy is turning 4 next month! 

For almost 2 months I've known we're doing a Spiderman theme (he introduces himself as Spiderman and "shoots webs" and anything and everything).  I was tickled to start pinning ideas; here's what I've saved so far.

Spiderman gift bags

Cake idea
Seems easy enough

Or we could do cupcakes

Table settings

Cool wall!

Party hats

Spider Cupcakes

Superhero Suckers

Spiderman Cookies
Potential favour idea

Superhero Masks

Birthday Shirt

Spiderman Pizzas
Might do instead of burgers and dogs

Goodie Bags

Spiderman Lunch
A special lunch on his actual birthday

I love planning his birthday (no knock against Alyssa, she's just not into much yet so themed parties aren't worth it...yet).  I like trying to come up with fun things to do (I have 1 game planned that I hope the kids will like).  Now, don't go thinking I'm going to spend lots of money on a 4 year old's birthday.  We're going to do the same as last year and just have people over to the house and the kids play.  It's low key, simple, but a lot of fun! 

Any suggestions on games?  Favours?  Or any other ideas I should consider?
