Headscratchers / Banjo-Kazooie: Nuts & Bolts

• Ok, so why did Banjo and Kazooie never bother to fix up their house in the eight year gap between Tooie and Nuts & Bolts? Why did they live in it after Gruntilda had blown it up and turned the place into an entire dump? I mean, how on Earth could they stand to still live in it without it getting repaired? How does it not bother the two that they're living in a run down old building and never bother to fix it up? Granted, Jolly Roger did fix it at the end of Nuts & Bolts, but why on Earth did the two live in that dump for eight years without repairing it until that point in the series?
  • It helps to emphasize the fact that the two just let themselves go after so many years of not being in another game. Or perhaps they did fix it up, but let it go into disrepair after seeing no reason to clean up.
