Dee stopped crying, Dwin went on (for the sake of simply being better at everything) a little longer. No help from outside came and seconds later the little, furry tank's computer rebooted to plan the next set of actions. She lay still - all things considered - her sister was not that bad of a pontoon to be on top of. Dee's gurgling was just the right background ambience to think things through. 

Brumm... brumm... brumm....

Tank's enginge started revving, Dwin wiggled and...

WROOOOOOOOMMMM....

She got off her sister - pawing, clawing, kicking, squashing - all in, sparing nothing. On the other side she was - nearly toppled over herself - and bumped her nosed against the den's wall. 

Obstacle conquered!
