My youngest daughter, Olivia, turns 7 today. How is it even possible that my BABY is 7?! Over the weekend we celebrated her with a fun Spongebob Squarepants Birthday Party. It was filled with family and friends, Krabby Patties, balloons, Bubble Buddies and lots of laughs! Without further ado, check out the party that I put together, as always, on a budget! Free printables available at the bottom of this post.

As always I set up a fun themed table:

If you’re looking for cake inspiration, you should definitely look her up. The cake not only looked amazing, but it was one of the best tasting cakes we’ve had in the middle. And the devil is in the details and inside the cake we were surprised with a fun yellow and pink pattern! You NEED to check out Miss Trendy Treats YouTube Channel  where she shares video tutorial for delicious treats, include this amazing cake!

So cool, right?!
Spongebob Birthday CakeSpongebob Birthday CakeI created the Krusty Krab using a friends lobster cage. I created and printed the flags. I used my Cricut to cut out a seashell and lettering for the Krusty Krab sign. A broken butterfly net donated the pole. And check out those amazing Krabby Patties! I really wish these were my brainchild, but they were totally the creation of my friend Krista and they were the hit of the party! Seriously, everyone loved these things. A step-by-step tutorial will be coming soon, courtesy of Krista.

Of course I made some fun water bottle labels as well:

We bought yellow popcorn boxes and used a Sharpie to draw on the facial features. Googly eyes were hot glued in place, along with two teeth, which were cut from regular white paper. I filled them with Spongebob themed items, such as a punch balloon, whoopie cushion, kazoo and lollipop. I also made some “Make your own Bubble Buddy” labels for the bubbles.

For the other food table I filled buckets with fruit and chips. I made Jello Jigglers using a Spongebob kit that I found in the local grocery store. I also made Plankton Pretzel rods, which were super tasty and placed them in a “Chum Bucket” that I personalized with my Cricut and vinyl.

I also made the banner and the Bikini Bottom sign, which is just a styrofoam wreath and ribbon. I used my Cricut Explore to cut out the “Bikini Bottom” letters and hot glued them in place. I used 3M Command Strips to hang it for the party and then easily removed them afterwards!

Spongebob Themed Birthday Party IdeasThe tablecloths, plates, cups, Spongebob Lollipops and Spongebob Pinata came from Oriental Trading. The other  Spongebob themed items for the goodie bags came from Party City.

I also had a dozen balloons and a “Free Balloon Day” sign. All of the kids loved picking a balloon to bring home.

And that’s our DIY Spongebob Squarepants Birthday Party! Do you have a Spongebob fan that would have loved this party?

I did have one other idea that I totally forgot to execute and I’m kicking myself now! I had a huge furniture box that I planned to put an “Imagination” sign on and put markers inside it and let the kids have at it. I don’t know how I totally forgot about it on party day, but I know it would have been a hit. I mean, kids LOVE boxes!
