Ok, what you have to do is go to the Inner-Space Shrinking Machine, you need to have the space suit, so into the area with all of the empty "space". Go in with space suit and walk over by the shrinking machine. Put the mouse/arrow thing right up against the seats that look like beans (up against the walkway thing) until it says exit. You'll come to an AWESOME room that you have shrunken to get into. You'll see a rocket and there's the inner space shop. I believe that is the only wat to get in now.
