It's hard, but with no time limit, you can choose with patience when to throw them.
If you reach boss with above 50 lifes and have some luck... it's done

Thanks Neromix, anyway I think it was a bug, beacause I collected it on level 10.
I've tryied it again today and after some minutes I have earned the badge doing it the same way as previous ones.

Citizen Snips
Dude! You just completed the Citizen Snips achievement in Ancient Origins{flying fish} and won the Citizen Snips badge and 30 points!
Yummyyyy I like this game a lot, played some time ago another game called "Pax Galaxia" I think that game was better than Nano War, because you were able to give orders to your planets, so the strategy was more important than the speed or your movements.
Anyway... 5 stars from me, well done guys!!!!
OMG!!!!!!! FINALLY!!!!!!
Dude! You just completed the Fish Thankfulness achievement in Dolphin Olympics 2 and won the Fish Thankfulness badge and 60 points!
