Poison Ivy's tower consists of one whole structure. The tower is built apon a 8 x 6 baseplate colored Dark Green. The tower is identical to the Hufflepuff Tower in the set 4737 Quidditch Match; but is slightly shorter. It also has the same colors as the Hufflepuff tower. Various plants and vines are composed from the bottom of Ivy's lair, to the top. Though the tallest peak of the tower sits a golden minifigure statuette. Poison Ivy can stand or sit on a brown 6 x 2 LEGO piece. The builder of the set can rearrange the plants any way he/or she likes. A rare cloth vine is used in this set; it is colored Bright Green.
Robin's Motorcycle is identical to Bart Blaster's motorcycle; though Robin attaches his grapple gun to the clip at the side of the cycle, instead of dynamite. Flame stickers are used on the front of the motorcycle.
Poison Ivy has captured Bruce Wayne with the help of her best friend Harley Quinn and trusted ally Bane; she has imprisoned Bruce inside her lair. Only Batman's sidekick Robin can save Bruce and defeat the villains.
Robin, Poison Ivy, Bane, and Bruce Wayne appear identical to their appearances in 6860 The Batcave. (Though Bane does not carry dynamite; instead, he carries plant fertilizer, in the shape of a hose nozzle. The nozzle is colored yellow).
Harley Quinn appears identical to her appearance in 6857 The Dynamic Duo Funhouse Escape, though she carries a pistol; like her 2008 variant. However, she does not carry her giant hammer; like in the set 7886 The Batcycle: Harley Quinn's Hammer Truck.
