You can create a little thing on the wall to hop up into the grey/black place beyond the walls. Only, it is a fun way to go into it!
Step 1:Put your wardrobe backwards against the wall.
Step 2: Go into it and get a rug (DO NOT use the big purple rugs, they do not work!) and put the rug on the ground in the grey.
Step 3: Go on the rug and jump up into the grey and then stay there. Put the rug into the attic.
Step 4: Put the rug back down onto the ground. (so it would be higher then before)
Step 5: SLOWLY AND CAREFULLY slide the rug into the wall half way. It has to be the rug direction being the l-o-n-g way.
IF YOU MESS UP AND THE RUG GOES ONTO THE GROUND IN THE HOUSE: Send it to the attic again and put it back down (in the grey).
Step 6: Get another rug when your a level higher in the grey and repeat steps 3-5.
If this doesnt seem to work at all and you REALLY feel like bugging me to come to your estate to help, you can PM me with a SF code
Good Luck!
