These are no ordinary fishes. Each of them has a spike that it uses as a weapon against its kin. As you probably know, competition underwater is very intense, so don’t be surprise to find out everyone is fighting fiercely in the sea. Plunge into the epicenter of the action and prepare to stab your opponents until you die. The one who will remain in the end will become the winner. Do you have the guts to defeat everyone else? Don’t worry if you weren’t lucky last time – you can always try again!
