A mouse trick

There were  2,900,090,987,598 mice that lived in a world.  One day a bad mouse that wanted to be alone and claim the land had a plan.  It started by saying let us do some thing scary everyone did go except one that the bad mouse didn't notice. When one mouse got scared. the bad mouse said "  Scaredy Cat then 2,900,090,987,596. All got scared and said " AAAAAAA here come the cat" He thought that the plan worked but one other mouse said "look at me I'm still here." He did the same trick and it DIDN'T work. He knew the trick and made the other mice come back because there was not cat.
