It’s time to get your build on! This Saturday, October 18, your local Toys R Us is hosting a Batsignal Lego build event. From 12-2, kids 5 and up (that means you, too) can build their very own Bat-signal. Considering that the Bat-signal has only showed up in Lego form in the Batcave set (6860), you may want to grab as many of the little ones as you can and head on over to Toy R Us this weekend. Get there early, too. Because, it’s one per customer, quantities are limited and it’s probably going to be pretty busy.
