Blue LEGO Friends set with red train engine

I lost my blue LEGO Friends set yesterday around 3pm near the playground behind the High Rockies Community Center on Main Street. It's a small blue brick train set, about 6 inches tall when built, with a bright red engine and a white sticker on the front. The bricks are a bit scuffed from lots of pretend play, and I think a couple of blue bricks and a tiny yellow flag piece are missing. This set was a gift from my sister and really means a lot to my kid; they're anxious about it and I just want to see it back in their hands.
