DIY Final Lap Mario Kart Costume

Sharing is caring!

Are you looking for a super simple costume that you can make for your kids? If so, this DIY Final Lap Mario Kart Costume is perfect for you! This costume took me about 3 hours to make, and will probably not take you as long because honestly, I’m not that crafty, and I did some things the hard way!

We also created this super cute DIY Zero Ghost Dog Costume Tutorial if you want to check it out!

My son had to come up with a unique costume for his youth group costume contest, and I knew it had to be something I didn’t have to sew, as well as something that I could throw together quickly before youth group (because I suspected I would procrastinate, which I did). The entire costume cost about $40 at Walmart and I bought a little more than I needed, so you could probably cut it down to about $30.

Oh, and in case you’re wondering… he won the contest! Yay us!

DIY Final Lap Mario Kart Costume Supplies:

  • 1 yard Dark Green Felt For Shell Base
  • 1/3 yard Lighter Green Flannel (I would have gone with felt but they didn’t have any)
  • 1/3 yard Yellow Felt or Flannel (banana peels optional)
  • Small Chalk Board
  • Chalk
  • White Paint (to paint chalkboard frame)
  • Stick (we used a fishing pole)
  • Black Yard (to hold sign and to hold cloud)
  • Yellow Shirt (I paid about $8 for a yellow thermal)
  • Hot glue gun and glue sticks
  • 1 bag of quilt filler stuffing (I used a pillow to stuff the shell, so you may want to get two bags or go easy on the cloud)
  • Cardboard box big enough for your child to get inside.
  • 1 black 8×10 sheet of felt (for eyes and smile on the cloud)
  • Headset
  • Goggles (our store was out of these)

How to make your DIY Final Lap Mario Kart Costume:

Step 1: 

Cut out your oval turtle shell from dark green felt. I found that doubling the cloth and leaving it connected at the bottom made it easier to stuff)

Step 2:

Cut out your shell designs from lighter green felt or flannel.

Step 3:

Hot glue your shell design to the shell. As you can see from the final picture, I trimmed the designs before adding them. I was in a hurry, and wish I would have had more time to do these.

Step 4: 

Stuff your shell with filler and hot glue the edges. Don’t go to the top on either side. Start on one side and glue about halfway up, then start on the other. You will end up trimming some of the bottom layers once you get the top glued. Just make sure you don’t overstuff the shell.

 Step 5: 

Cut your cardboard box to look like a cloud, then poke two holes at the top of each side for the yarn to go through so your child can “wear” the cloud. After you’ve added the string hot glue the stuffing filler to the box. Make sure you have your child wear the cloud, so you can accurately measure the string. We tucked the shell into the cloud, but you could make the cloud hang low enough to go below the shell.

Step 6:
Paint your chalkboard frame with white paint (if you need to) and drill a hole in it for the string. After it dries write First or Final Lap on the chalkboard.

Step 7:
Attach the shell to your yellow shirt. I bought a shirt just for this costume so I sewed the shell directly to the shirt. I attached it to the neckline, but I would also recommend adding stitches to the sides and the bottom so it doesn’t pull too much on the neck. You could also use safety pins (I didn’t have any).

 Step 8:
Attach the chalkboard to the fishing pole or stick using yarn.

Step 9:
Cut out banana peels from the yellow felt/flannel.

Step 10: 
Cut out eyes and smile and hot glue them to the cloud.

You could also use thin electrical tape or marker to line the front of the shirt/shell.

So what do you think of our DIY Final Lap Mario Kart Costume?

We hope you enjoy your night! Happy Halloween 🙂
