Scooby Doo Birthday Party Ideas

1. Mystery Solving Scavenger Hunt

Turn your Scooby-Doo birthday party into an exciting mystery adventure! Create a scavenger hunt with hidden clues leading to a final “treasure.” Write out fun, age-appropriate riddles and place them in envelopes around the party area. Kids can work in teams, just like Mystery Inc., to solve the mystery and find the missing Scooby Snacks or a hidden treasure chest filled with party favors. To add extra fun, have an adult or older sibling dress up as a Scooby-Doo villain to give out hints along the way!

2. Scooby Doo Birthday Party Invitations

Set the mystery in motion before the party even begins! Design creative Scooby-Doo birthday invitations shaped like:

• A magnifying glass, revealing party details when tilted.
• Scooby Snacks box, with a fun message inside.
• Mystery Machine van, opening up to show the time and place.
  For a DIY option, print invitations with Scooby-Doo’s paw prints leading to “You’re Invited!” at the end. Use fun phrases like, “Jinkies! There’s a mystery to solve at [Child’s Name]’s birthday party!”

3. DIY Mystery Machine Backdrop

A Mystery Machine photo backdrop makes the perfect centerpiece for your party’s decorations! Use a large piece of cardboard or a fabric banner painted in Scooby-Doo’s iconic blue and green van colors. Add details like orange flowers, headlights, and the “Mystery Machine” logo. You can even cut out the windows so kids can pose inside for fun, themed pictures. Set up props like magnifying glasses, speech bubbles with “Zoinks!” or “Ruh-Roh!”, and a plush Scooby-Doo for extra fun.
