Mr. Krabs gives you a key to the warehouse when you tell him that you found all the
pickles. Can you please tell me where the warehouse is.

in the industrelal park

just go to the bus stop in industrial park and you will find a whirlpool pad and use it
you will be thrown in the super speed pad and use it, go on and go on just don't fall and
you will find a little path that leads to the old factory
