Not sure how this started. I was going through some storage boxes and pulled out some vintage Kenner Star Wars playset parts - Land of Jawas, Imperial Attack Base (Hoth), etc. My daughter started setting up her Peanuts figures in them....and wala! Quite the fun mashup of properties.
And later on, the Scooby Doo gang joined the party.
I'm thinking an AT-AT painted like the Mystery Machine would be pretty darn cool.
What mash-up would you do with toys?
