The LEGO Batman Movie 70921-1 Harley Quinn Cannonball Attack stages an intense confrontation between Batgirl and Harley Quinn.

The truck also boasts opening doors and an opening hood for added realism. Batgirl must dodge attacks amidst two Gotham City building mini-builds, each packed with play-starting details like an ATM element, a dynamite component, and a hinged ladder. The set includes four minifigures, with Batgirl and Harley Quinn prominently featured, plus a rat figure, capturing a chaotic street scene from Gotham.
