So, Scooby's birthday party gets ruined—shocker, right? One second the gang's all hyped for cake, then poof, lights out. When they flick back on, the cake’s straight-up gone. Classic Mystery Inc. luck.

You’re basically playing detective with Scoob, clicking around this little party scene for clues. There’s confetti everywhere, half-eaten snacks, and of course, Shaggy looking way too guilty (but let’s be real, he’d never steal cake—he’d just eat it on the spot). The art’s got that goofy cartoon vibe, and the puzzles are simple but kinda charming, like figuring out which guest left weird footprints or why Fred’s ascot is suddenly… glittery?

It’s short, silly, and exactly what you’d expect from a Scooby flash game. Perfect for killing five minutes while pretending you’re not too old for this. The real mystery is why the thief didn’t just take the veggies instead.
