A big heads up to the parents of Lego fans.

You may be interested in a free event at Toys R Us stores this Saturday, Oct. 27.

From noon to 2 p.m., most Toys R Us locations will have a "Lego Bricktober" event.

Kids will get to help build a Lego Monster City and each child will receive a free exclusive Monster City Mini Pack.

The event is being advertised nationwide, but just in case, I reccomend calling your Toys R Us before heading out -- or even telling the kids.
