Drew's Sea World bathroom...

Ok so Andrew is starting to get the hang of going to the bathroom all by himself, kind of. Today he was in there for a really long time so I went to check on him. When I walked in I realised he had found a pencil in there and was drawing all over. There were drawings on the front of the door, the back of the door, the toilet and the walls. When I asked him why he did that he said "it wasn't nice in here." Then I asked what he'd drawn and he told me that it was Sea World. How could I get mad at that?? Oh but believe me I did. It took me FOREVER to get Sea World off the walls and the door, I even had to use a Mr. Clean eraser for the really dark marks. Lets just say as I was stitting there on the bathroom floor scrubbing the walls and the door I was NOT happy.
