When my son came to me and told me he wanted a Spiderman birthday party theme, I was thrilled. When he was three, he also wanted a Spiderman party and I remember coming across so many fun ideas — but they weren’t age appropriate at the time. Flash forward to him turning nine and the possibilities were endless!
With that said, just like any party, it still took a lot of brainstorming to come together. Not to mention, this was his first party since we moved countries so I had to reset my mind of how to run certain activities. New house, new area, different crafts available. There’s been a lot to coordinate and think about!
Being familiar and a fan of the Spiderman movies, I had a million concepts swirling around my brain from searching Pinterest. Spiderman or Avengers training? Web target shooting with silly string? None of these however inspired me. In the end, I looked towards the formula of the Secret Agent Party I threw my son for his 6th birthday.
During that party, I sent the kids on a scavenger hunt mission that led to dusting for fingerprints, uncovering secrets with hidden ink, escaping a villain, getting through a laser maze, and eventually diffusing a pull string piñata. It was a lot of work but absolutely epic.
With that formula in mind I knew I needed to create a party with the following basic things: scavenger hunt, villains, secret clues, and a Piñata.
After brainstorming and jotting down notes about the various Spiderman movies, I came up with a plot, using aspects of Spiderman: No Way Home.
Spiderman Birthday Party Plot
The theme of the Spiderman birthday party revolved around three main characters: Spiderman, Green Goblin, and Dr. Strange.
Spiderman and The Green Goblin Send a Video
The party began with Spiderman sending my son a video (thanks Cameo!), and wishing him a happy birthday. I wrote a script and sent it to both a Spiderman cosplayer and Green Goblin cosplayer. After I received the videos, I edited them together and edited the special effects, music, and sound effects.
During the video, it got interrupted by The Green Goblin. The Green Goblin attacked Dr. Strange at the Ancient Sanctum and tried to steal his Magic Box.
Why?
Because he wanted to erase the memories of every superhero across the multiverse!
During their battle, Dr. Strange managed to send the magic box into a portal but as the Green Goblin threw his pumpkin bomb at Dr, Strange’s hand, his portal ring flew into the portal too and multiplied!
Now, the Kid Avengers needed to find the rings, open the portal, and destroy the magic box before the Green Goblin would find it first.

Dr. Strange Arrives
As soon as the video finished, Dr. Strange (played by my wonderful husband) arrived with their first clue. The very first clue alerted the kids to the strange appearance of the Goblin’s Pumpkin Bombs around the neighborhood. The first one was spotted dropped somewhere in our backyard.
To create the Pumpkin Bombs, I created a template on Photoshop and printed it on sticker paper. I used my Cricut to cut it out. I painted the inside of empty Christmas bulb ornaments green and then added the sticker on top of the ornament.
Nerf Guns and Hulk Smash Wall of Clues
Running off to the backyard, they discovered the Green Goblin’s pumpkin bomb and a page from the Daily Bugle notifying them that my son’s aunt had turned into Sandwoman!
Inside the brick wall I had made, there were clues with the recipe for Sandwoman’s cure. The kids had to shoot the bricks out using Nerf Guns. I overestimated the ability for nine year olds to aim though and only one of them managed to hit a loose brick.
The great part about the wall though is I had a backup plan: Hulk smash it! The kids all came up and took turns punching the wall to remove the clues. They really enjoyed this and were excitedly running up to punch away!
Sorting the Clues
There were sixteen clues in total inside the wall. After collecting all of the clues from the wall, the kids headed inside into the Avengers lab (aka our dining room) and gathered around the table.
The clues were in a rhyme and they had to match the phrases based on the rhyme.
The rhyme was:
“Six are sour, juice their power
Brave the web course, to find the magic sugar source.
From a butterflies wings, a mystical powder swings.
No time to dwell, go to the lab and mix together in a 6 cup water well.
Sprinkle then stir, to finish the magic cure.
The Goblin’s been busy, the cure won’t work if it’s fizzy.”
After they figured out all of the clues, they headed back into the backyard to brave the obstacle course my husband had set up.
The Spiderman Birthday Party Obstacle Course
Our backyard space was limited so my husband worked in the best of his abilities and made a fun course for the kids. The kids walked the balance beam, crawled through a web tunnel, threw an arrow through a giant ring, made a jump, and jumped through the hoops. Throughout the course, there were 6 lemons, 4 jars of sugar, and 2 containers of butterfly pea flower powder for the kids to collect. They each had to find and collect one item as they made their way through the course.
If you have a larger backyard space, you can do far more challenging obstacles or skip the course and just do a scavenger hunt throughout the yard.
The favorite part of the course was throwing the arrow through the ring. Even as the party was wrapping up later, the kids were heading into the yard to do this part again.
Once the ingredients were collected, the kids all headed back inside to the Avengers Lab.
Spiderman Birthday Party: Defeating the Villains
Creating the Cure for Sandwoman
Inspired by Spiderman: No Way Home, the kids had to head to the lab to create a cure for Sandwoman.
The cure was a recipe for lemonade mixed with butterfly pea flower, an edible natural color changing ingredient. We used to use it at our restaurant for some fun cocktails! When mixed with water, the pea flower is blue. However, once it mixes with something acidic (in this case, lemon), it turns purple.
Before they could make the lemonade though, they had to test the jars of sugar. After all, the clues had said the Goblin may have tainted some of the ingredients.
For the recipe, the kids only needed two jars of sugar. Thus, in the other two jars, I had mixed baking soda in with the sugar.
The kids poured bottled lemon juice into the test tubes and then tested them for a chemical reaction with a small scoop of the sugar from each jar.
In retrospect, the kids could’ve also tested the butterfly pea flower powder. To test this, I would recommend having one container with the butterfly pea flower powder and another with some other powder (flour, sugar, anything really!) mixed with purple or blue food coloring. The kids could test each sample in a tube of water and then add lemon juice to see which one changes color.
The science experiment portion was a hit and the kids had a lot of fun testing the ingredients. They took turns testing and even when the jar had already been tested, they were just as excited for their own turn.
Afterwards, we filled the mixing bowl with water and added the pea flower powder. Then, they each got half a lemon to squeeze into the bowl and watched the color change before adding the sugar.
They poured the “cure” into multiple testing tubes before heading down to the beach by our neighborhood. If you have a neighborhood park, you could also head there!
Curing Sandwoman
When the kids arrived at the beach, they found my sister with a beige cape draped over her and after some convincing, “tricked” her into trying the cure. She dramatically fell the ground as the cure took over and healed her, throwing her cape off behind her.
Afterwards, she handed the kids a bag with half of the magic Dr. Strange rings in them, as well as the next clue: to Stop Doc Ock.
Defeating Doc Ock from Spiderman
Off in the distance on the grass, was my son’s uncle who was dressed as Doc Ock with a blue ball. The kids all had to spread out and surround him in a circle before tossing the ball to each other while saying the phrase, “You will not become a monster”. Doc Ock controlled the game by telling the kids to go faster. If they dropped it though, they had to move closer to him as he acted real menacing. Eventually when they were close enough or had tossed it enough times (truly however many you want based on how the pace of the party is going!) he was suddenly cured.
Once he was cured, he handed the kids the other bag of Dr. Strange Portal Rings along with their final clue.
Opening the Portal at The Kid Avengers Headquarters for the Spiderman Birthday Party
Discovering the Dr. Strange Portal
The final clue altered the kids to one more pumpkin bomb located near the driveway of our house. We all walked back and once the kids found the pumpkin bomb, they put on their magic rings to open the portal.
With Dr. Strange, they all pointed at our garage door and did the Dr. Strange portal spin with their fingers. My husband secretly held the garage door opener in his hand. He had a lot of fun starting and stopping it, teasing the kids, until their power was strong enough to open it.
Inside the portal was The Ancient Sanctum with the magic box piñata, modeled after the box in Spiderman: No Way Home.
The Dr. Strange Box Piñata from Spiderman: No Way Home
The kids all stood around inside the garage, taking turns to destroy the piñata. Afterwards, they headed inside the house to go over their winnings while we set up the garage for cake!
Spiderman No Way Home Birthday Cake
For the birthday cake, I challenged myself (as I always love to do!). The main cake was actually fairly simple: I used a sphere shaped mold to create a ball and covered it in a beige-bronze toned frosting.
The challenging part, was the chocolate box I created surrounding it. I first created an outline for the design and printed it, placing it underneath baking paper so I could trace it.
Using melting chocolate, I traced out the image. Then, with the help up my mom, I placed the chocolate around the cake. This is definitely not a one person job! It was vital I had somebody else hold the chocolate pieces up while I drizzled more chocolate on the edges to connect each side. Creating the chocolate molds took at least three hours but it was worth it. I absolutely LOVED the final product.
Decoration Ideas for a Spiderman Birthday Party
For the party, we had four different locations that I decorated.
Kid Avengers Headquarters
For the headquarters, I created a Kid Avengers sign by first creating the logo in Photoshop and then using my Cricut to cut out stencils of the letters. I hand painted the sign and then we used Velcro to attach it to the wall.
Around the room, I taped blue and red tissue paper and set up all of the Avengers themed toys my son has collected. By the windows, I draped white streamers to represent spiderwebs.
On the table, I put a fun recreation I made of the Daily Bugle with a headline about my son being named leader of the Kid Avengers and his trip to the Ancient Sanctum, showcasing pictures from previous trips to California Adventure by Disneyland.
Setting up the Headquarters (not including crafting the sign), took less than an hour. It was very easy to throw all of that up!
Spiderman Lab
In the dining room, I covered the table with a white plastic cloth and printed out a simple sign. I set up two kids science kits, a measuring cup, mixing bowl, juicer, and cutting board. This set up took only a few minutes.
The Backyard Brick Wall and Obstacle Course
In the backyard, we set up the brick wall I created that was full of clues. To make this, I painted bricks on a cardboard box and taped it to a standing garden trellis. This allowed for it to stand and left space behind the bricks for them to fall out. I cut out each of the bricks that had the clues on them and then popped them back inside the wall.
As for the rest of the yard, my husband set up a fun course for the kids and we put each of the clues throughout the yard, trapping some of them inside the spiderwebs.
Dr. Strange’s Ancient Sanctum
The Ancient Sanctum was by far the most time consuming to build and took me nearly a week to design, with the help of my mom. The Ancient Sanctum was inspired by the one at California Adventure in Disneyland.
Inside our garage, we still had a wall full of boxes from our move. Instead of figuring out how to stash them elsewhere, we stacked them and covered them in grey plastic table covers to create a broken wall. Once placed and taped securely to the boxes, I got out my brown sharpie and drew lines across to outline the stones.
To create the falling broken rocks, we cut up and scrunched up different sizes of the grey and gold plastic table covers we had. Once satisfied with their appearance, we taped them up and attached them to the wall. After all of that was done, I hit the craft store and bought plenty of fake leaves to throw over and around the wall!
On the other side, I needed to cover up the rest of our storage! So, I draped a gold plastic table cover over it and painted it to look the like doors at the Ancient Sanctum.
For the floor, I printed out an outline I created, recreating the ancient symbol that is drawn across the ground at the Ancient Sanctum. I created a step-by-step sheet of which lines to draw and my mom and I sat on the floor with chalk, drawing out the symbol in the center of the room.
At the garage door entrance, I used a balloon arch and attached door streamers to it to create the portal, trimming them to length to ensure nobody would trip!
Finally, the piñata I created was hung above using very secure string, stretched across the room.
