One of my favorite toys for the kids are their Fisher-Price Trio blocks (similar to legos). I love how creative they can be! My son received the complete batman set for a Christmas present last year; and while he loves playing batman, he also builds guns, fishing poles, and most recently a grill—complete with little briquettes and a grill lighter!
Middlest also joined the fun by constructing her own set of grillware.
And we all enjoyed some tasty grilled plastic hot dogs. Yum!
