Remember those grow toys from when you were a kid? The ones that start off like tiny little figures and then expand overnight in water to many times their size. Now instead of lame neon colored bugs there’s the Batman Grow Toy. This caped crusader starts off a little over 2 inches and within 24 hours immersed in water he will expand to 6 times his size. Sure Robin might be a little jealous and Alfred’s now going to have to make a larger Batmobile, but such is the price for supersized justice in Gotham City.
