The Island in the region of Rushmore was quiet save for the sounds of the indigeonous lifeforms, primarily geese, though not to forget the trees and grass and all the other plant-life that flourished on the island's virgin landscape. This peaceful tranquility was soon interrupted... thousands upon thousands of sleek black crafts skimmed across the water each measuring no more than a metre-wide, 6 metres long and barely 10cms tall.
One by one these crafts beached themselves on whatever beaches they could find and after a few seconds out of each of the crafts streamed lots and lots of little white mice they each ran up the beach to give those behind some room. These mice were to make their new home on this Island after years of wondering in the vast open seas of the World, however it was not going to be that easy. While the geese occupied the internal areas of the Island, the beaches and coastline were practically owned by the Seagulls, opportunistic carnivores.
This was a problem for the mice, the reason? With so many mice on the beach it was like they were setting up an all you can eat buffet for whatever seagulls were in the area. The seagulls eyes popped out of their sockets with glee as they saw the mass of mice, soon one by one they started to dive towards the mice. Some explosions disrupted the seagulls dive some where hit and killed others were clipped and fell, others managed to fly limp-wingedly back. The rest backed out of their as fast as possible, they couldn't understand what was happening only that they didn't want it to happen again.
The crafts all had cannon-like defenses that emerged out of the roof of the craft and fired at the gulls, after a minute or so of the firing (depending on howmany gulls there were to start with) the gulls where either dead or running away, a victory for the mice. After the firing of the cannons the last of the mice exited the crafts. The Island was now teaming with billions of mice, the crafts fell apart on the sand of the beaches and each mouse worked together to carry the pieces of the crafts up onto the Island proper. Grassed areas were soon pilled up with pieces of the crafts.
The mice went hard at work and over time used the parts of the craft to build mice cities, each beach site formed a city nearby, each city contained millions of mice, despite the large cities none of them exceeded the size of a city of a 100,000 humans though when scaled wasx infintely larger.
