Fisher Cat

How could you say no to this poor fisher cat here? He's been watching these fishes for hours, trying to... catch them with the help of his special little claw-shaped... gadget, with no success! It's time for you to intervene and, using the arrow keys, to master handle that tool for catching lots and lots of fishes from the water tank that you have there, avoiding, as much as you can, all the other non interesting sea creatures swimming there!
