When we were in Florida, the kids enjoyed trading minifigs with the employees. Do they do that at LL California? Are there any "rules"? For example, does the minifig being traded need to be an actual minifig produced by Lego, or can it be a "masterpiece" built by the kids from various minifig parts? I'm not sure if we have many head to toe authentic minifigs around this house anymore, but I thought I heard that was a new requirement at some of the Lego Discovery Centers.
