This is the first box to go of the 4 new boxes the buns received in their room remodel. Note how the lower left side is collapsing and how the buns have renovated the box from having 2 entrance holes to pretty much a scenic view on 3 of the box sides. This box is now history and has been removed from their area since they might get hurt if they attempt to climb on the box.
This shows how far they have progressed on box number 2. Their method of box deconstruction seems to involve focusing on one box at a time; they focus their energies for maximum timely results, rather than spreading out the destruction over time and space. Single-minded little destructo-bunnies. Will they have any boxes left by Xmas, or will they need to have Santa Paws put some under the tree? Stay tuned for more adventures of the box buns.
