Son's Birthday Party

There are a ton of party idea websites for kids.
Check out birthdaypartyideas.com and they will have
alot of ideas- if not for Indiana Jones then adventure
or explorer or jungle parties for sure. Check out
Family Fun magazines website too - they have
alot of great ideas I know for jungle parties. Go you your
local library and they will probably have Bday party
idea books. You can also look on Oriental Trader website
and buy safari hats or rubber snakes, etc....for cheap and they have great customer service is you are not happy with anything or want to return. Sounds like great fun!

Sounds like fun. Maybe an adventure party would work. An obstacle course in the backyard that the kids have to "rescue" something or somebody. I'm not sure where you could get them, but it seems someone should have hats similar to Indiana Jones. You could have fun with "eye ball" soup and some of the other foods. There's a recipe for worm cake that has gummy worms in it and you have to dig in the "dirt" -- chocolate pudding and cake. Decorations could be a dessert idea, or something similar. We did a really cheap party two years ago where the favors were part of our activities. The kids painted something I found at Hobby Lobby. Our party favor "bags" were pails with shovels. The kids got to dig with them at the party. If you have a sand box, or something similar, they could dig for treasure. I hope this helps. Just a few ideas that came to mind. Have fun. I know the kids will.

you should do a scavenger hunt! or bury treasure and have a map.....

Do a fun scavenger hunt with items that will lead to a puzzle or a booby trapped treasure chest. something adventurous and extreme like Indiana. They should all have whips too!

I guess you'd have to customize your cake...you could probably do some sort of screen print from a picture relatively cheap at King Soopers or Safeway or you can dress up an ordinary cake with creepy crawly things.
Invitations can be some sort of map invitations (try Paper Wares they always have a great selection of invitations...you can either print them yourself or handwrite them or have them print them)
You could decorate inside or outside with Tiki Torches and Maps & Masks. Isn't Indiana Jones an Archealogist. I know that in the movie they were in Nepal and Cairo so you can steal ideas from there native decorations.
Indiana Jones Music soundtrack or theme song is at I-tunes.
You could maybe do some sort of obstacle course game where each kid goes through it and tries to get a prize and at the end. When the child gets up closer to the prize then roll a giant ball (workout ball) at him let him dodge it to get to the prize (sort of like in the movie)
Favor bags could have rubber Snakes, Spiders and Scorpions (US TOY) inside of it along with candy (Sucker Rings that look like gems).

Good Luck, I hope your son enjoys dressing up like Indiana Jones.
