For an interesting twist with themes take the Finding Nemo Party Supplies mixed with another theme creating a unique event.  Do your children like Finding Nemo? For fun get a plastic kiddies pool, add rubber duck's or plastic fish if you can find them and mark one in permanent ink on the bottom. The children can take turns picking until someone finds the marked one to win a prize. Children will love cooling off in the pool when the game is over. Or make it a day on the beach by adding sand and letting them build shapes of their favorite sea creatures from the show. Don't forget to play the movie at this party. Make your Birthday party original!
