I just adore this Under the Sea party filled with summer-worthy kids’ activities, cute craft projects, and hints of sailors and pirates, too! It’s a joint celebration for brothers Cole, age 3, and Tate, age 1.

Cole and Tate’s printable banner and all-blue streamer backdrop are just the thing to announce the Under the Sea theme.

Outside, an awesome color-it-yourself cardboard pirate ship is an activity center in itself – perfect for keeping little sailors entertained!

How cute are these kiddos at play! I love that the ship has a “real” steering wheel.


Brooke used printable buffet cards to label not just the party food, but also the craft stations, like these temporary tattoos.

The kids decorated white lunch bags with foam fish and stickers, and at the end of the party, Brooke filled the each child’s bag with favors to take home.

Can you have any more fun with anything else as simple as a big ol’ bucket of bubbles?! Brooke added a bubble wand-making activity, too, where kids twisted pipe cleaners into a wand shape.

The fish-and-splash kiddie pool is a huge hit!

One sure sign you did a good job planning the kids’ activities: adult time! : )

Brooke created a life preserver from a foam ring and red ribbon, which the kids used to play water balloon toss.

Blue balloons, netting, and handprint fish make the indoor decor sea-worthy! (Cole made the handprints with his grandmother before the party.)

Rice Krispy treats become little pirate ships with the addition of hand-drawn skull-and-crossbones flags.

Peanut butter and jelly sandwiches are picture-perfect made on goldfish bread!

Cole and Tate’s adorable cake was made at Whole Foods. Brooke says, “they asked me to bring a copy of the invitation and they matched it. All of the frosting was natural so the colors were a little more muted, but still very true to the theme!”

This picture of Tate’s feet sticking out from under his high chair is so precious! Brooke says, “I made the high chair ribbons – I just picked up fun ribbons at Michaels, cut them and laid them out at random (it was hard for me not to measure and follow a pattern, but it was fun!) Then I just used a zig-zag stitch on my machine. I cheated a bit to attach it – it’s just taped on.”

What a wonderful party – thank you so much for sharing, Brooke! Happy birthday to Cole and Tate!
