Piranhas are meat-eating fish that are obstacles in the Omicron game. They are vicious predators that mainly appear in the second level of the jungle chapter of the game. They come in groups, and will attack anything swimming on sight. Even if you're capable of attacking underwater, the piranhas are too quick and work together. The best thing you can do is to avoid them, either by swimming as fast as you can, or by just staying out of the water. You can handle at least a few piranha, but an entire pool filled to the brim with them is best avoidable. You could even try distracting them with something tender and edible like meat. There will be obstacles that they will be willing to eat.
