No matter how many aquariums you have in your house, even if one has an octopus and sting ray, you'll need some genuine Octonauts decorations to let all the partygoers know that they just stepped into the world of their favorite cartoon. Best of all, these decorations look great and provide a genuine feel of the cartoon, plus they go up easily. So if you're looking for a hassle-free way to transform your party, these decorations are the ticket. You won't even need scuba gear.

Birthday Banner

With Captain Barnacle, Peso and Kwazii looking on, the crew in this banner invites everyone to come celebrate your child's birthday in the ocean! What delicious forms of cake and ice cream await in this underwater world? Looks like your child and his fellow Octonauts will find out.


This plastic Octonauts tablecover does double duty. First, it keeps the cake and punch from spilling on your table, and second, it's full of colorful images that your kid and their guests will love. It's like eating with the entire crew of the Octopod!




When everyone is done riding dolphins or chasing Moray eels and ready to settle down for some cake, make sure you have the serving ware fit for royalty, or at least some ocean adventurers. With our Octonauts plates, the kids will be even more excited to finish off their cakes to see the cool image beneath. In addition, we have sets of disposable knives, forks and cups to fill and refill with any beverage you serve. For the inevitable mess that happens at any kid's birthday party, the Octonauts-themed napkins are so much fun the kids might even like cleaning up.


Great parties don't just happen, and a pack of cake-hungry bundles of energy don't just have a good time. You know that it takes some careful planning and coordination to make it all come together. It's a lot of work, but we here at BirthdayExpress are here to help. We've looked high and low for just the right activities to make your Octonauts birthday party an event to remember. The only problem is that the guests will have had so much fun that they won't want to leave! Fortunately, there's always next year.


We've put an oceanic spin on a classic birthday party activity. The kids will love taking a swing at the Octopod in hopes of breaking open a treasure trove of candy and toys. This complete kit comes with everything you need to play a traditional game of piñata.

Party Favors

You've put a lot of work into making sure your child enjoys a truly seaworthy birthday party, and you know their friends and guests helped make it a success. Be sure to show all their little friends just how much you appreciate their company by giving them a party favor to take home. These thoughtful gestures are a great way to ensure that your party under the ocean waves will be remembered for a long time.

    Yes, they're loud and lead to a little too much zaniness, but when you're young, there are few things more exciting than a birthday party blowout. These are customized for all the Octonauts out there, coming with the signature logo that lets others know these partygoers know their way around the ocean.


Personalize It!

Once you've picked up the cake, strung up the decorations and made sure all the parts in the Octopod are running, you'll probably wonder if there's anything else you can do to make your little one's birthday all the more special. We have a number of popular products that can be personalized, and doing so is easier than you may think. All you have to do is find an adorable picture (keeping it to just one might be hard), create a message and we'll do the rest!


This heavy-duty vinyl sign will welcome guests to the party, and when your little one sees their face on the banner they'll giggle with joy! If you've been looking for a truly personal statement, this is it.


There are few things a toddler wants more than cake and ice cream. Imagine how much more spectacular that dessert will be when it's served on a custom plate featuring the birthday boy or girl's cute face! Just upload the photo and we'll do the rest!


Some people go to great lengths to make extravagant centerpieces. But the cutest one in town, featuring your little one's adorable picture, might be the easiest to make. Like our other custom items, all you do is upload an image and we do the rest!

Favor Boxes

Now you can send your child's friends home with a party favor box that has the birthday kid's smiling face right on it. It's a great way to say thank you for coming to the party and to get everyone excited for next year!


Thank–You Notes

After your child has opened all the presents and you've had time to clean up, and after both of you have taken a nap, it'll be time for one of the most important parts of any birthday: writing thank you notes. To help you with this task, we have great styles to convey gratitude and re-live the underwater adventures had at the party. You can choose the fun and simple Octonauts thank you notes or even create custom thank you notes that will feature any picture you choose, along with a brief, personal message.
