Yeah but Mom's got Good Teeth....

I am wandering down a hallway - I need to go through this restaurant to get something I need- oddly it is dark. I'm not sure if it is not open this early or what. I'm my way back there is more light, and I can see I am on an open roof. As I pass through the restaurant, I step on some things. Apparently they have this place setup for a birthday party. As I step into the light, I notice I've dragged all kinds of presents and a santa clause and things, so I need to put them back. I get lost on the roof and a guy sees me, another guy is coming for me, and I am hiding but the other guy shows him where I am. I feel brave and try the copycat routine with him
