Low level character & dino destroyers!!! They rip your high end armour apart before killing you, after have killing your dino if you were unlucky. Always check before crossing rivers. (Especially a plague on The Island Map)
These piranhas are SOOOO annoying!One time I was passive taming and Equus and it ran into the water, Then about 2-4 piranhas came up and killed my Equus! I was so sad and I went and killed them. WildCard, If you see this lower the percentage of piranhas. Thank You!
