Batmobile Pontoons

ANGLE ON LAKE

The Batmobile plunges into the lake!  A brilliant SHOWER OF BLUE SPARKS
explode across the water's surface as the vehicle disappears.  For a
moment, all is still.

ANGLE ON PENGUIN IN AIR

The Penguin looks down, "clucking" contentedly.  His expression
suddenly starts to change.

ANGLE ON LAKE - HIS P.O.V.

Slowly re-emerging on the surface of the lake:  The Batmobile!  Its
roaring turbine engines propel it forward, now supported by TWO
HYDROFOIL PONTOONS!  The makeshift craft speeds over the water at
speedboat velocity.

The Batmobile reaches shore, churning up chunks of mud as the pontoons
contract and the car bounces onto the park road.  The protective blue
light has been extinguished.  From either side:  two Hood Cars
approach, machine guns blazing!
