The Dink Network

Help, I am really stuck. At the first of fb1, at the upper right, there is a cave behind the old lady's house. In the room that looks like it is divided by a mirror, how do you get through? I can't figure it out. Please help

This room is just for viewing. You don't have to pass it.

I think it was a mirror project the Wesley was working on,,,Very cool concept! I have seen this idea in some XBox + PS2 games. Getting it down pat in Dink could be problematic unless someone can really figure out the coding to write!
