The Prehistoric landscape was shifting in more ways than one. The temperature fluctuations affecting the vegetation and the seemingly dwindling numbers of inhabitants were certainly a cause for concern, but to Chet there was a more pressing issue at hand.
His bunker permit had once again been denied by the jungle planners.
They had long since given up the pretense of a legitimate reason for their refusal. They had started with something to do with the infeasibility of collecting and hardening enough vegetation to create a "flying rock from space"-proof shelter. The second application, in which Chet had emphasized the use of mud and "smaller, earth-resident rocks," was met with some concerns over how if he was granted a bunker permit then everyone would want one and there simply was not enough materiel to support the inevitable demand.
(Chet knew they were pandering to him with that one - he could only dream that his neighbours would open their eyes to the gravity of their situation.)
Finally, this latest request was denied on the grounds that there was a new species of small reptile that seemed to wander through the area he wanted to build and the planners needed to keep an eye on it.
But Chet knew the real reason.
His bunker would be an eyesore and the planners were not going to have a giant mound of leaves and mud ruining the picturesque cretaceous landscape. As if the giant rocks hurtling through the sky would leave the trees and flowers untouched, thought Chet haughtily as he set to work on his next submission.
This time he would add a garden on top to soften the impact.
