Scooby Doo party for 6 year old - need help with games.

[DarkDarkWood]

DS loves Scooby Doo so wants it as a theme. We have 12 guests coming and i want to do a mystery but have zilch in the way of imagination. Can anyone please help me to think of some scooby clues? I'd love to do a little mystery game but can only think of 'meddling kids'.

What about a mystery hunt around the house or party venue following clues to look for hidden items or scooby snacks? We did a clue mission hunt instead of an Easter egg hunt last weekend and the kids adored it so much we had to keep thinking up new places to hide things and new clues.

Thanks Seaweed, that's what i'm thinking but can't seem to 'invent' any clues.

I'm sure some inspiration will come to me!
