Invitations you can use to sound the Octo alert include:

Some suggestions include:

• Mini Octonaut figures: Perfect for topping a birthday cake with the whole crew. 
• Cardboard Octonaut cupcake toppers: Ideal to bring an Octonaut flair to single-serving cupcakes or other treats. 
• Octonaut cake pops: The Octonauts look adorable in cake-pop form, and making and decorating these treats can be a fun project for you and your toddler.  

7. Let them expend some energy and smash a pinata

Know what your child needs after cake and punch? More sugar, obviously! Try setting up a pinata full of candy that everyone can take a whack at. 

Check out this adorable DIY Octonauts pinata in the shape of the Octopod. It’s an awesome Octonauts birthday party idea to make with a little paper mache and creativity. 

8. Play Octonaut party games to keep them entertained

Time for party games! Luckily, it’s easy to find printable templates that you can use to occupy your child and their guests.

Our favorites include:

• Pin the Patch on Kwazi: Like pin the tail on the donkey, but Octonaut-themed!
• Octonauts Bingo: These cute Bingo printables feature Octonaut characters instead of numbers, which is great for little ones still learning to count. 
• Octonaut coloring pages: You can’t go wrong with crayons, and these printable Octonaut coloring pages give your child a chance to express their creativity.  

You’re going to need a large party space to ensure the kids have plenty of room to safely play these Octonauts games. Don’t have tons of space at home? Don’t worry, Peerspace has you covered! One of our favorite spacious kid’s party places is this kid’s event space in Honesdale, PA with room for 100 guests, an indoor padded playground, and plenty of seating.

9. Go on a treasure hunt

If you’d prefer a more interactive party idea than printables, try staging a scavenger hunt with clues hidden across your venue! 

This family staged an interactive Octonauts treasure hunt for their toddler’s birthday, with prizes including pirate treasure and mini telescopes. It’s a fun Octonaut birthday party idea to engage your child and their friends. 

Need a spacious, fenced-in backyard to set up your own Octonauts treasure hunt? Then Peerspace has you covered! Check out this large, fenced-in backyard in Hacienda Heights, CA, as one example.

10. Throw on those Octonaut water wings and hit the pool

11. Play in the sand…with a cause!

If you’re lucky enough to live near the ocean, you could hit the beach to play in the sand! But if you don’t have a beach nearby, you could always just set up a sandbox. 

This family staged a game to save “turtle eggs” buried in the sand, which can help your child feel like a real Octonaut on a mission. Plus, you’ll get to snap cute photos of them while they help out their animal friends. 

12. Pass out Octonaut party favors 

After your toddler’s friends have all enjoyed an afternoon of Octonaut-inspired fun, it’s time to send them on their way with a goodie bag. 

Creative party favors you can try at your Octonauts party include: 

• Fish crackers: Goldfish crackers are great for snacking on the car ride home (and getting lost in the seat cushions. But that’s someone else’s problem.)
• Eye patches: Kid-sized pirate eyepatches can help party guests channel their inner Kwazii. 
• Gold treasure coins: Because everyone loves a little pirate treasure – especially when it tastes like chocolate.
