Growing up in my house always meant big birthday celebrations. Nothing extravagant or over-the-top like pony rides or petting zoos, but always lots of fun with friends and family, an overly-frosted homemade cake, and an occasional wacky birthday theme thrown into the mix.

Many sale racks later, I have stumbled across some randomly fantastic birthday themes that are a break from your traditional Spider-Man or Cinderella. If you are tired of traditional themes, here are five fun and unique ideas for your kid's next birthday celebration.
