As Elliot pointed out, it was definitely a stretch for the theme, however, we went to the Trading Posts at Legoland and traded our mini-figures.
The main part we went there was because Nana bought us each a mini figure to trade. Just about all the employees have another mini fig. On their shirt so we could go on rides and then trade if we had one. I traded 7 times witch was the most, and i ended up with a sheriff with a hat, gun and tiny legs.
