Peeing spiderman

This is one of the most funny photo about spiderman. As we know, spiderman doesn't want the others know who he is.So, he will not wear the professional spiderman costume in the public even he wants to pee.There is a question, how does he solve this urgent problem?
This spiderman really want to the other people know him. But why he doesn't take off his hood? At the same time, he is looking the others all the time. The most interesting thing is that there is a white color spider bag on his back. What kind of things in it.
I am not sure whether this is a advertising or not. Because there is also a cute bear or cat behind him. Three of them are peeing at the same time. Is this a rinal advertisement?
