When the Knights of Ni demand a shrubbery, it will be easier to find one, it seems.

Except the knights who say Ekky-ekky-ekky-ekky-z'Bang, zoom-Boing, z'nourrrwringnmmm are too tall to hide in just shrubberies - so their goes that career.
But then, there will be no place for a whole lot of other species to live, either.
What comes after forests is a catastrophic extinction event.

In my dictionary 'forestall' but who knows?
