Buried Treasure Hunt
Fill a kiddie pool with sand and then bury small treasures such as pretty rocks, sea shells, fake jewels and large
plastic coins. Give the party guests sand shovels and sifters to find the buried treasure in their “beach”. Let them
take the treasure home as a party favor.
Beach Ball Icebreaker
Blow up a beach ball and write questions all over the ball - fill up as much space as you can with as many questions as you can think of.
Have guests sit in a circle and throw the ball to each other. When someone catches the ball they have to answer the question that their right thumb is touching.
Sample questions: What is your middle name? Scuba dive or surf board? If you were a marine animal what would you be? What sand sculpture would you like to make? Have you ever been to the beach? Ever been stung by a jellyfish? If you had a million dollars what would you buy first? What would you change your name to? Chocolate or vanilla? Favorite color?
Limbo
Use a decorated broomstick handle or pole for guests to limbo under. Have a contest and give away lei’s or small
prizes to the winner.
Mystery Fishing Game
Kids fish for prizes in this fun game! For the "water" use a large appliance box, hang a sheet across a doorway, or cover a table so that the "fish" (and the person in the water) are hidden from view. Tie a string to a stick and attach a clothespin on the end of the string. Birthday party guests take turns "casting" the line into the "water". The person in the "water" puts small gifts, favors or candy on the clothespin and then tugs the string to signal that there is a "fish" on the line. Then kids pull up the line and retrieve their prize. This is a simple but fantastic birthday party game that kids adore! Have lots of prizes because kids will want to do this birthday party game again and again.
