Given that Batman fights Mr Freeze in the film most of Kenner's figures were based around ice or heat. Far fewer were based around him battling Poison Ivy.
Ambush Attack Batman is one of those rare exceptions. Batman is in some nifty looking green gear (so presumably he's fighting Poison Ivy). The cape pivots at the back of the waist allowing the whole thing to swing up and point two missiles forward.
This is a fun one, I like the cape missile thing - I've not seen that before - but this is maybe not a massively essential purchase... unless you're making a plant themed Batman figure collection and need something to go with Jungle Tracker Batman from the Batman Returns line.
