This darling OCTONAUTS THIRD BIRTHDAY PARTY was submitted by Leah Davies of I Heart Table Art. What a cute party! I absolutely love the soft color palette used in it! I also love the fun mini water tank table decorations. This party has so many fun ideas that any adoring Octonauts fan will love! The Octonauts party ideas and elements that I like best from this delightful birthday celebration are: The cute Octonauts cake The cute Octonauts cookies The darling Octonauts cupcake toppers The fun water tank decorations The cute Ocotnauts mason jars and MORE!
