The animation took over 17 hours to render. I used 25 fps with a maximum resolution. I made the camera follow a spline around the front of the mouse, while it explodes then the model combines again at the end. the Animation rendering stopped unexpectedly 3 times. so i had to restart it  from the ending point. luckily the files didn't corrupt when this happened. i managed to change the codec of the file so it would insert to windows movie maker; which I used to merge the files and compress it.
