Birthday Party DIY – Spongebob Theme!

For those of you with children!

I have two small boys. Toddlers. They already know how to press all my buttons and destroy the entire house with a marker. But every day they still lift me up and make each day exciting and fun and filled with love. So when their birthdays were approaching, I knew I wanted them to really enjoy it!

Their birthdays are 2 weeks apart which makes throwing parties hard for me. I wanted to save money but also really celebrate their special days. We decided to do a joint party smack dab in the middle of their actual birthdays. When my husband recommended we do a Spongebob theme, I knew it was perfect.

I decided I would do a DIY party that would bring Bikini Bottom to our front door.

Here are some of the decorations I made and the final results!


Sponge Bob Time Cards

This idea came from Pinterest! They made great props for the boys to hold for birthday pictures! I made one for each boy for how old they were.

Here’s my supply list:

  • Large foam board
  • Acrylic Paints
  • Card Stock Paper
  • Spongebob themed font (free downloads from the internet!)
  • Printer
  • Scissors
  • Glue stick
  • Sponges
  • x-acto knife

I decided on these backgrounds after some google image searches. These seemed to be the easiest to replicate. I applied my base coat and after it dried, reapplied. I cut cheap sponges in the shape of the shells and flowers and cut a wavy stencil out of card stock. I created the words by using Word and a free font I found online. I blew the words up as big as I could and used the landscape setting. Then I cut each letter out (I know. It’s tedious! I found that an x-acto knife helped with cutting out the small details in the letters and in the sponges.) I then painted the wavy lines on the blue time card and was sure to stencil it out first to ensure it was symmetrical to the other lines. For the yellow card, I simply dragged a paintbrush in light yellow paint in crash wiggles all over the board and lightly dragged a thin line of dark brown paint along the edges to replicate the original! Then dip your sponges in paint and place with moderate pressure on the board. It DOES NOT have to be perfect! Do touch ups if needed but do it sparingly. I found the effect looked better when it wasn’t perfect. I used a second (round) sponge to do the circle in the flowers on the blue board. Then using a glue stick, I glued the letters down. Voila! It’s done!

Chum Buckets

These little buckets were perfect to hold snacks. The idea came from a google search for Spongebob party ideas. The only buckets I could find were at Walmart and came in glaringly bright silver or black. I chose the silver and decided to hand paint them to “fix ’em up”. I was going to use a handy-dandy template that Nickelodeon has on their website but my buckets were too big. Using the template as a guide, I stenciled in the letters and painted the doors with some acrylic paints. Then, I sprayed them with a sealant.

Spongebob food ideas!

These were lots of fun!

The top left is “Jellyfish Jam” – It is simply black cherry jello poured into clear cups. Using a glue stick and the image from a google search – I simply cut and glued the labels on the cups. This was one of the kids’ favorites!

Kelp Soda – This was from an idea off of Pinterest! They’re small bottles of sprite with green bendy straws. I used a dab of my hot glue gun to secure the labels (found on google images) and a piece of tape to secure the straws. So cute!

These Styrofoam cups were perfect for holding our french fries (we had Krabby Patty Hamburgers too!). Using the Krusty Krab logo, a label template, and some computer magic, I created these perfect fit labels.

My Spongebob cupcake toppers were also found on google images! I simply cut these out, used a hot glue gun to glue them together and inserted a toothpick in the bottom. Piece of cake!

We also had Krusty Dogs (hot dogs), Pineapple fruit salad, Plankton Pretzels (Green chocolate covered pretzel rods) and “Coral Bits” (snack mix!)


DIY Pinata

To make this awesome pinata all you need is:

  • A large, empty cereal box
  • Yellow wrapping paper
  • Yellow streamers
  • Coat Hanger
  • A glue stick
  • Tape
  • Spongebob face (Google Images)
  • Scissors

Fill your box with candy or small toys and tape it shut. Then wrap it in yellow wrapping paper. I had to do two layers because it was see-through. Tape to secure. Print and cut out the eyes, mouth, and nose and glue down about center on the box. Taking the roll of streamers, slide the scissors under and cut 12 or so layers off at once. Then cut slices halfway into the streamer to give a ruffle effect. Glue each strip down, overlapping slightly. Getting it to hang was the tricky part. We used a wire coat hanger (pushed it through the box) and hung in a doorway. The box held up pretty well and I would definitely do it again!

party bags

Goody Bags

These goody bags were fun to make!

Bags – Yellow bags from the dollar store. I cut out pictures of the cartoon duo and glued them on with a glue stick

Bubble Buddy’s Bubbles – These bubbles also came from the dollar store but got a Spongebob makeover with a quick label. I secured with a dab of hot glue.

The Party Hats- Nickelodeon has a template available on their website (plus lots of other cool ideas I tried below!) You can visit their website here!! Just print, cut out, and attach some elastic bands!

Paper Build-a-Spongebob – These were all found on google images! I cut out the pieces and put them in Ziploc bags. I created a label, customized with the character they’ll build and stapled that to the bag.

We also put in Spongebob rice Krispies treats (dyed yellow with candy eyes and icing smiles) and small thank you cards that I printed and cut myself. Finally, we found a Bikini Bottom dollar on google images. I glued chocolate coins to these and gave out “cash prizes” for the winners of the party games we played!


The Galley Grub Sign

It simply had to be done! I used poster board and painted the base coat leaving the brush marks noticeable for the appearance of texture. Then printed and cut out the letters and glued ’em down! We punch holes in the corners and used twine to string it up!

You’ll probably also notice we used a blue plastic table cloth and cut out paper flowers and taped these down. We also used a Pineapple as a centerpiece!




Paper Plate Jellyfish – This idea came from Nickelodeon’s website and was super easy to make! I didn’t have a plastic pink table cloth so I made do with the fringe technique from the pinata using dark pink streamers and glued them around the inside edge of the plate. I used a light pink streamer and glued across the top of the plate. Then I painted the dark pink spots with acrylic paint. Finally, I used three shades of pink streamers and cut various lengths and glued them to the inside of the plate. I crinkled them a bit and strung them up with fishing line!

The Krusty Krab banner was made on Microsoft Paint and printed on card stock. I cut out each square, punched holes in the corners and strung it up with some twine.

The seaweed streamers were simply green streamers that were twisted and taped vertically along the walls in sets of three (various lengths). We already had the boat bookcase!


I hope these ideas inspire you to create your own DIY party. I will never forget my boys walking in the room in awe. I was so happy to see them have a blast celebrating their birthdays!

I am a 25 year old from Western North Carolina interested in phobias and fears after dealing with Anxiety and Panic Disorder over the last few years. It had such a debilitating effect on my life. I realized how much of life I was missing out on due to fear. I hope that by instilling courage in myself, I can instill courage in others to face their own fears and live life to the fullest capacity!
