Lock it

Miss 3 has been industriously emptying her entire wardrobe every day and then filling it with toys. This has been driving me completely nuts, as it takes quite some time to re-hang clothes back on wardrobes and put peg puzzles back on their boards.
The latest time she did it and I told her off was quite funny.
Me: Stop taking your clothes out of your wardobe!
Her: NO.
Me: *stunned silence*
Her: You need to put a wock (lock) on it. There's a wock on the bathroom door. You need to put a wock on my cupboard.
I think she's right.
