Crafting Your Own Bowser Costume

If you’re feeling creative, here’s a basic rundown on how to make your own Bowser costume:

  1. Jumpsuit: Use yellow fleece or sweatsuit fabric to create the base of the jumpsuit. Stuff the arms and legs with batting for a more muscular look.
  2. Shell: Cardboard covered in green paint or fabric is a budget-friendly option for the shell. Alternatively, craft foam can be used for a more lightweight and durable shell. Don’t forget to add spikes!
  3. Accessories: Make a spiky tail out of rope or felt, and craft cuffs and a spiky collar to complete the look. Use craft foam or papier-mache to create a menacing Bowser mask.

Other Bowser-themed Halloween ideas

Bowser costumes are fantastic, but the world of the Mushroom Kingdom offers a treasure trove of Halloween inspiration! Here are some ideas to expand your spooky celebration:


  • Koopa Troopas: Gather your friends and create a mini Koopa Troop! Wear green shells and jumpsuits, or get creative with cardboard shell backpacks.
  • Princess Peach: Channel the iconic damsel-in-distress with a pink dress, crown, and flowing blonde hair. Bonus points for a sassy attitude!
  • Luigi: Luigi often gets overshadowed by Mario, but his green attire and signature Poltergust 5000 vacuum cleaner make for a recognizable (and slightly spooky) costume.
  • Goombas: These adorable brown enemies are surprisingly easy to pull off. Wear a brown bodysuit or sweatpants, and create a simple Goomba head from cardboard or felt.
  • Bowser Jr.: The mischievous offspring of Bowser adds a fun twist. Craft a tiny spiky shell, wear overalls, and don a mischievous grin.


  • Mushroom Kingdom: Transform your home into the vibrant world of Mario. Create cardboard cutouts of iconic landmarks like Peach’s Castle or warp pipes. Decorate with red and white polka dots, clouds, and plenty of mushrooms!
  • Fire & Fury: Bowser’s fiery personality can inspire fiery decorations. String orange and red lights, create paper flames, and even add a cardboard Bowser cutout breathing “fire” (made from orange crepe paper).
  • Coin Crazy: Coins are a staple in the Mario universe. Scatter gold cardboard coins around your party space or create a giant coin piñata filled with treats.


  • Koopa Troopa Relay Race: Divide into teams and race while wearing cardboard shell backpacks.
  • Princess Peach’s Cakewalk: Set up a cakewalk with prizes themed around the Mario universe, like plush Koopalings or miniature stars.
  • Mushroom Hunt: Hide plastic mushrooms around your house or yard and have guests compete to find them first.

Food & Treats:

  • Princess Peach Cupcakes: Decorate cupcakes with pink frosting and tiny crowns for a touch of royalty.
  • Fire Flower Cookies: Craft sugar cookies in the shape of fire flowers (red with yellow centers).
  • Goomba Snacks: Make mini brownie bites and decorate them with white candy eyeballs to resemble Goombas.
  • Mario & Luigi Pizza: Order a half-and-half pizza – one side with pepperoni for Mario and the other with green peppers for Luigi.

These are just a few ideas to get you started. With a little imagination, you can create a truly memorable Bowser-inspired Halloween celebration!
