Shark, deciding that she might have a chance, chased the remaining deer as fast as she could. She caught up with a weaker one that was trying to cross the stream (about 5 feet deep) and leaped, but she was also starting to swim so she missed it's neck, instead she locked on to it's back leg and brought it down. It started drowning so she brought the half dead deer back to shore and dragged it up on land. (Not sure if the next part is possible but) Although she liked eating meat, she didn't want any animal to suffer for too long so she made the killing bite while it was on the ground.
Then, taking it by the leg, dragged it back to where Sapphire and Luna where waiting. "Look what I caught!" She exclaimed happily. "This should last about a week."
