Wow, what a task. I asked my 4 year old son what he would like his 4th birthday party theme to be and his response (after an appropriate pause) was...Buzz & Woody, Spiderman, Batman and oh yeah Transformers. Keep in mind that he has never seen the last 3 on TV or in movies so I am guessing the influence of other kiddos and "boy toys" has had a bit of an impact here! 
When I asked him how Mommy was supposed to do a cake w/all of those characters his response was "just put them all on there." So, in the spirit of going w/the party he wants, that's what I am going to do.
Now, I am looking for any ideas and tips or if there are any other threads where others have tried to pull off any or all of these themes. If so could you please direct me to the correct thread or if they don't exist, I would love to hear any ideas you might have (even examples of other parties that might work w/this theme would be great)!
Thanks so much in advance for your help!
