A Boy’s Octonauts Inspired 3rd Birthday Party

By  | Last Updated:  

“Sound the Octoalert!” This Octonauts inspired boy’s 3rd birthday party by Leah, of I Heart Table Art, is swimming with creative details to honor her oldest son, Jack.  Leah achieved a clean, fresh look for the party styling by selecting ocean shades of blue and green with generous splashes of white.  You’ll notice the cake and other dessert ideas, as well as the decorations and printables, all coordinated with both the theme and color scheme.  Don’t miss a single picture of the ocean dwelling creatures and décor, beautifully captured by Peggy Saas Photography.

Styled around amazing printable graphics and a backdrop by Pretty and Print, Leah designed an under-the-sea, ocean floor dessert table that surely inspired shouts of “jumping jelly fish” and “flappity flippers”! Delightful blue and white cake stands, paired with white plates, made perfect display pieces for gorgeous desserts.  Sweet little Octonauts characters top a beautiful cake by Sweetharts Cupcakes. Isn’t the kelp detailing perfect?

I love how the Octonauts’ faces were expertly captured in fondant for both the cupcakes and on enticing sugar cookies by Charming Treats. Their zips of color added to the overall energy of the table, too. Kids get so excited to see their favorite characters as part of the desserts!

Other dessert options included blue and green cake pops which looked impressive lined up on display. Custom printable wrapped candy bars were another wonderful addition to the dessert table; I especially like the contrast of the darker blue on these pedestals.

Boy's Octonauts Birthday Party Candy Jar Ideas

One of my favorite DIY ideas from this ocean adventure was the candy jars!  Leah made these by painting the lids of glass jars and affixing small character figurines.  I think the colorful candy choices look amazing shining through the clear glass!

Boy's Octonauts Birthday Party Aquarium Ideas

I also loved Leah’s ingenuity in creating the aquariums by using glass vessels, colored rocks, plants and Octonauts characters.  These little details made the dessert table an underwater masterpiece!

Boy's Octonauts Birthday Party Beverage Station Ideas

Colorful tassel garland by Piece of Cake Parties & Celebrations highlighted a sweet beverage station. Seafoam green pedestals handsomely pair with the blue ombre Jello in this area. I love how a few Octonauts toys were included in the display to tie this space to the dessert table and overall theme.

Boy's Octonauts Birthday Party Table Setting Ideas

For the main meal, Leah set up a delightful dining area under a water colored tent with beautiful honeycomb balls.  Lovely pops of color were added to the tables and chairs (children’s table and chair hire from Piece of Cake Parties & Celebrations) with a spread of confetti dots from Favor Lane.  Polka dotted straws in milk glasses paired with pale aqua plates for fun place settings that multiplied the water color effects.  I love that each plate was topped by an Octonauts hat from Favor Lane. Each guest received lunch in a clear clamshell with a cute, custom “crew meal” label.

Boy's Octonauts Birthday Party Favour Ideas

At the conclusion of their ocean adventure, guests received darling favor boxes (Favor Lane), with custom favor tags and fun Octonauts inspired loot—flag, notebook, eye patch and snack.

Sound the Octoalert? False alarm; it’s just the squeals of delight at this incredible boy’s Octonauts inspired 3rd birthday!
