My Buying Guide on ‘Under The Sea Party’

Hello fellow party planners! My name is [Your Name] and I recently organized an amazing ‘Under The Sea’ themed party for my friend’s birthday. It was a huge success and everyone had a blast! Planning this party can seem overwhelming, but fear not, I am here to guide you through the process. Here are some tips and tricks to help you throw the perfect ‘Under The Sea’ party.

Theme and Decorations

The first step in planning any party is choosing a theme. For an ‘Under The Sea’ party, think ocean-inspired colors such as blue, green, and turquoise. You can also incorporate sea creatures like fish, seahorses, and mermaids into your decorations. I found it helpful to create a Pinterest board for inspiration.

For decorations, you can hang streamers or balloons in your chosen colors to create an underwater feel. You can also use fishing nets as tablecloths or wall hangings. And don’t forget to add some seashells and starfish as accents around the room.

Invitations

Invitations set the tone for your party, so make sure they match your theme. You can find many cute ‘Under The Sea’ themed invitations online or make them yourself using cardstock paper and foam sea creature stickers.

Food and Drinks

The food at your party should also follow the ocean theme. Some fun ideas include making “sandwiches” with graham crackers, peanut butter, and jelly or creating octopus hot dogs by cutting slits into the hot dog before boiling it. For drinks, you can serve blue punch or make fruit skewers with blueberries and pineapple chunks to resemble little fish.

Games and Activities

No party is complete without games and activities! For an ‘Under The Sea’ themed party, consider setting up a craft station where guests can decorate their own sea creature masks. You could also have a treasure hunt using plastic seashells filled with candy or small toys as prizes.

If you have access to a pool or beach area, you could plan some water games like a relay race with inflatable dolphins or a diving competition for older kids.

Party Favors

Sending guests home with a small token of appreciation is always a nice touch. For an ‘Under The Sea’ themed party, consider giving out mini beach buckets filled with treats like candy fish, seaweed snacks, and bubbles shaped like sea creatures.
