The third little pig made his house out of.....

[Karen]

Yes, but think of the fun we could have redecorating.......constantly.

I know - a certain sister would be taking the tiles and sorting them by color, a certain nephew would take it apart just because he could ... and how much sleep would the little ones get with a wall of temptation, never mind a bed that you can take apart and reconfigure ... Lady'd be all confuzzled if we moved the couch daily ...

The couch wouldn't be moving daily, it would be morphing constantly, and it wouldn't be very comfy for a puppy.
