The thing that l love about kids so much is their imaginations. It doesn't matter that it's a Woodzeez bakery with two McDonald's toys and 3 Lego princesses. It doesn't - they are all friends.
Later, Lego Cinderella takes her carriage over to a Doug & Melissa dollhouse to have plastic food picnic with fairy friends, a ladybug bathtoy, and baby shower favor babies. It works. All their toys don't have to be perfectly matched. Most kids don't care about that stuff and that's what makes it fun.
