Look to the left of the construction worker sitting on the rotating donut to see a grab-able explosive crate. Grab this crate and fly into the wall in front of you, and super-ooch over the train tracks towards the cop car. There is a police man and a girl wearing a bikini, bomb her with this crate 5 times (after each successful bombing, press R1 to reset and Select to reset the level) in order to unlock Demolition. This is just like how you unlock Ed the Cow.
Launch at Granny and drag her down into the subway with you onto the tracks.
