21 Ocean Party Favor Ideas that Will Make a Splash

If you’re looking to throw an ocean themed birthday and want your guests to remember the special occasion well past the party date, then you might want to consider sending them home with a party favor bag. The best favor bags are ones that contain well thought out gifts that are fun for kids and can also be used over and over again. Big or small, the best favor bags help your guests remember your party for years to come. Pick out some goodies from this list of 21 under the sea ideas, fill up your bags, and thank your guests for being there.

And don’t forget your thank you tags!

  • Bucket and Sand Toys
    Instead of using a bag or a box for your party favors, consider putting everything into a sand bucket. This way, every time your guests go to the beach with their bucket, they will remember your ocean themed party. You can even add some shovels and other sand toys for a complete beach kit.
