Easy DIY Jurassic Park Toddler Costume + Wagon Cage
If you’ve followed our Halloween adventures, you know we love a family costume theme. And for Halloween 2025, we decided to go a little bigger. Like… Jurassic-sized. 🦖
Aydin transformed into our baby dinosaur, safely “captured” inside his very own DIY Jurassic Park wagon cage, while we completed the family theme around him.
The best part? This Jurassic Park toddler costume looks way more complicated than it actually is. I made a simplified PVC wagon cage with no power tools required, and the entire project took us about two hours and cost around $40.
So if you’re looking for an easy DIY Jurassic Park costume for a toddler, dinosaur-obsessed kid, or family Halloween theme, here’s exactly how we made ours.
What You’ll Need
Cage setup
- Toddler wagon (we used this wagon)
- 7 PVC pipes (¾-inch)
- 8 PVC elbow joints and 12 T-connectors
- Behr black matte spray paint
- PVC cutter
- Measuring tape
Cage details
- Jurassic Park logo (print this at a local fedex or CVS)
- High voltage sign
- Danger sign
- Silver yarn
- Faux greenery and vines
- Zip ties
- Optional: boxes
Easy Step-by-Step Instructions
Step 1: Build the frame
Start by measuring the length, width, and approximate height of your wagon.
Our cage was built using seven long pieces of PVC pipe that we cut into multiple smaller sections. The exact measurements will depend on your wagon, so I highly recommend sketching out your cage on a piece of paper first.
This made it much easier for me to visualize which pieces needed to be cut and where each elbow joint or T-connector would go.
Use the elbow connectors to create the outside rectangular frame and the T-connectors to add the vertical and horizontal cage sections.
Tips
It’s much easier if you draw the design out yourself on a piece of paper to make sure you get all the measurements correct. PVC is easy to work with, but it is much easier to trim a piece shorter than realize you cut it too short.
Step 2: Paint and decorate
Once you know the cage fits correctly, take the PVC frame outside and spray paint it with black matte spray paint.
Allow everything to dry completely before attaching it back to the wagon.
Once dry, add your Jurassic Park logo, danger signs, and high-voltage signs. I printed our Jurassic Park graphics locally and attached them to the cage.
Then wrap faux greenery and vines around parts of the PVC to give it that overgrown jungle look.
Step 3: Add details
To make the cage feel even more like something straight out of Jurassic Park, wrap silver yarn around sections of the frame to mimic an electric fence.
This adds a lot of visual detail without using anything sharp or unsafe around your toddler.
You can wrap the yarn loosely between the PVC bars and secure the ends with small knots or zip ties.
Step 4: Load the “dino”
Dress your toddler in a cozy dinosaur onesie – this is the one that we purchased linked here.
This is the dinosaur costume we purchased, and it worked perfectly because it was comfortable enough for Aydin to wear while sitting in the wagon and walking around throughout the night.
And just like that, you have your very own mini Jurassic Park dinosaur transport cage.
The Final Look
The entire build took roughly two hours and cost about $40. Huge thanks to Well, She Tried for the original idea. Their project gave me the confidence to make a version simple enough for any parent to tackle.
Why I Love Easy DIY Costumes
I used to think DIY meant complicated, but now, it’s my favorite creative outlet. From Aydin’s spaghetti & meatballs costume last year to this year’s Jurassic Park build, each Halloween reminds me that the joy is in making, not perfecting.
